SPDX: Convert all of our multiple license tags to Linux Kernel style

When U-Boot started using SPDX tags we were among the early adopters and
there weren't a lot of other examples to borrow from. So we picked the
area of the file that usually had a full license text and replaced it
with an appropriate SPDX-License-Identifier: entry. Since then, the
Linux Kernel has adopted SPDX tags and they place it as the very first
line in a file (except where shebangs are used, then it's second line)
and with slightly different comment styles than us.

In part due to community overlap, in part due to better tag visibility
and in part for other minor reasons, switch over to that style.

This commit changes all instances where we have multiple licenses (in
these cases, dual license) declared in the SPDX-License-Identifier tag.
In this case we change from listing "LICENSE-A LICENSE-B" or "LICENSE-A
or LICENSE-B" or "(LICENSE-A OR LICENSE-B)" to "LICENSE-A OR LICENSE-B"
as per the Linux Kernel style document. Note that parenthesis are

Create PHY Lib for U-Boot

Extends the mii_dev structure to participate in a full-blown MDIO and
PHY driver scheme. The mii_dev structure and miiphy calls are modified
in such a way to allow the original mii command and miiphy
infrastructure to work as before, but also to support a new set of APIs
which allow (among other things) sharing of PHY driver code and 10G support

The mii command will continue to support normal PHY management functions
(Clause 22 of 802.3), but will not be changed to support 10G
(Clause 45).

The basic design is similar to PHY Lib from Linux, but simplified for
U-Boot's network and driver infrastructure.

We now have MDIO drivers and PHY drivers

An MDIO driver provides:
read
write
reset

A PHY driver provides:
(optionally): probe
config - initial setup, starting of auto-negotiation
startup - waiting for AN, and reading link state
shutdown - any cleanup needed

The ethernet drivers interact with the PHY Lib using these functions:
phy_connect()
phy_config()
phy_startup()
phy_shutdown()

Each PHY driver can be configured separately, or all at once using
config_phylib_all_drivers.h (added in the patch which adds the drivers)

We also provide generic drivers for Clause 22 (10/100/1000), and
Clause 45 (10G) PHYs.

We also implement phy_reset(), and call it in phy_connect(). Because
phy_reset() is essentially the same as miiphy_reset, but:
a) must support 10G PHYs, and
b) should use the phylib primitives,

we implement miiphy_reset, using phy_reset(), but only when
CONFIG_PHYLIB is set. Otherwise, we just use the old version. In this
way, we save on compile size, even if we don't manage to save code size.

Rewrite the miiphybb (Bit-banged MII bus driver) in order to support an arbitrary number of mii buses.

This feature is useful when your board uses different mii buses for different
phys and all (or a part) of these buses are implemented via bit-banging mode.

The driver requires that the following macros should be defined into the board
configuration file:

CONFIG_BITBANGMII - Enable the miiphybb driver
CONFIG_BITBANGMII_MULTI - Enable the multi bus support

If the CONFIG_BITBANGMII_MULTI is not defined, the board's config file needs
to define at least the following macros:

MII_INIT - Generic code to enable the MII bus (optional)
MDIO_DECLARE - Declaration needed to access to the MDIO pin (optional)
MDIO_ACTIVE - Activate the MDIO pin as out pin
MDIO_TRISTATE - Activate the MDIO pin as input/tristate pin
MDIO_READ - Read the MDIO pin
MDIO(v) - Write v on the MDIO pin
MDC_DECLARE - Declaration needed to access to the MDC pin (optional)
MDC(v) - Write v on the MDC pin

The previous macros make the driver compatible with the previous version
(that didn't support the multi-bus).

When the CONFIG_BITBANGMII_MULTI is also defined, the board code needs to fill
the bb_miiphy_buses[] array with a record for each required bus and declare
the bb_miiphy_buses_num variable with the number of mii buses.
The record (struct bb_miiphy_bus) has the following fields/callbacks (see
miiphy.h for details):

char name[] - The symbolic name that must be equal to the MII bus
registered name
int (*init)() - Initialization function called at startup time (just
before the Ethernet initialization)
int (*mdio_active)() - Activate the MDIO pin as output
int (*mdio_tristate)() - Activate the MDIO pin as input/tristate pin
int (*set_mdio)() - Write the MDIO pin
int (*get_mdio)() - Read the MDIO pin
int (*set_mdc)() - Write the MDC pin
int (*delay)() - Delay function
void *priv - Private data used by board specific code

The board code will look like:

struct bb_miiphy_bus bb_miiphy_buses[] = {
{ .name = miibus#1, .init = b1_init, .mdio_active = b1_mdio_active, ... },
{ .name = miibus#2, .init = b2_init, .mdio_active = b2_mdio_active, ... },
...
int bb_miiphy_buses_num = sizeof(bb_miiphy_buses) /
sizeof(bb_miiphy_buses[0]);

Create PHY Lib for U-Boot

Extends the mii_dev structure to participate in a full-blown MDIO and
PHY driver scheme. The mii_dev structure and miiphy calls are modified
in such a way to allow the original mii command and miiphy
infrastructure to work as before, but also to support a new set of APIs
which allow (among other things) sharing of PHY driver code and 10G support

The mii command will continue to support normal PHY management functions
(Clause 22 of 802.3), but will not be changed to support 10G
(Clause 45).

The basic design is similar to PHY Lib from Linux, but simplified for
U-Boot's network and driver infrastructure.

We now have MDIO drivers and PHY drivers

An MDIO driver provides:
read
write
reset

A PHY driver provides:
(optionally): probe
config - initial setup, starting of auto-negotiation
startup - waiting for AN, and reading link state
shutdown - any cleanup needed

The ethernet drivers interact with the PHY Lib using these functions:
phy_connect()
phy_config()
phy_startup()
phy_shutdown()

Each PHY driver can be configured separately, or all at once using
config_phylib_all_drivers.h (added in the patch which adds the drivers)

We also provide generic drivers for Clause 22 (10/100/1000), and
Clause 45 (10G) PHYs.

We also implement phy_reset(), and call it in phy_connect(). Because
phy_reset() is essentially the same as miiphy_reset, but:
a) must support 10G PHYs, and
b) should use the phylib primitives,

we implement miiphy_reset, using phy_reset(), but only when
CONFIG_PHYLIB is set. Otherwise, we just use the old version. In this
way, we save on compile size, even if we don't manage to save code size.

Rewrite the miiphybb (Bit-banged MII bus driver) in order to support an arbitrary number of mii buses.

This feature is useful when your board uses different mii buses for different
phys and all (or a part) of these buses are implemented via bit-banging mode.

The driver requires that the following macros should be defined into the board
configuration file:

CONFIG_BITBANGMII - Enable the miiphybb driver
CONFIG_BITBANGMII_MULTI - Enable the multi bus support

If the CONFIG_BITBANGMII_MULTI is not defined, the board's config file needs
to define at least the following macros:

MII_INIT - Generic code to enable the MII bus (optional)
MDIO_DECLARE - Declaration needed to access to the MDIO pin (optional)
MDIO_ACTIVE - Activate the MDIO pin as out pin
MDIO_TRISTATE - Activate the MDIO pin as input/tristate pin
MDIO_READ - Read the MDIO pin
MDIO(v) - Write v on the MDIO pin
MDC_DECLARE - Declaration needed to access to the MDC pin (optional)
MDC(v) - Write v on the MDC pin

The previous macros make the driver compatible with the previous version
(that didn't support the multi-bus).

When the CONFIG_BITBANGMII_MULTI is also defined, the board code needs to fill
the bb_miiphy_buses[] array with a record for each required bus and declare
the bb_miiphy_buses_num variable with the number of mii buses.
The record (struct bb_miiphy_bus) has the following fields/callbacks (see
miiphy.h for details):

char name[] - The symbolic name that must be equal to the MII bus
registered name
int (*init)() - Initialization function called at startup time (just
before the Ethernet initialization)
int (*mdio_active)() - Activate the MDIO pin as output
int (*mdio_tristate)() - Activate the MDIO pin as input/tristate pin
int (*set_mdio)() - Write the MDIO pin
int (*get_mdio)() - Read the MDIO pin
int (*set_mdc)() - Write the MDC pin
int (*delay)() - Delay function
void *priv - Private data used by board specific code

The board code will look like:

struct bb_miiphy_bus bb_miiphy_buses[] = {
{ .name = miibus#1, .init = b1_init, .mdio_active = b1_mdio_active, ... },
{ .name = miibus#2, .init = b2_init, .mdio_active = b2_mdio_active, ... },
...
int bb_miiphy_buses_num = sizeof(bb_miiphy_buses) /
sizeof(bb_miiphy_buses[0]);

Now, various phy devices can be attached to each of these slots(mux).
The information about these devices is passed to OS via device tree.

SPDX: Convert all of our multiple license tags to Linux Kernel style

When U-Boot started using SPDX tags we were among the early adopters and
there weren't a lot of other examples to borrow from. So we picked the
area of the file that usually had a full license text and replaced it
with an appropriate SPDX-License-Identifier: entry. Since then, the
Linux Kernel has adopted SPDX tags and they place it as the very first
line in a file (except where shebangs are used, then it's second line)
and with slightly different comment styles than us.

In part due to community overlap, in part due to better tag visibility
and in part for other minor reasons, switch over to that style.

This commit changes all instances where we have multiple licenses (in
these cases, dual license) declared in the SPDX-License-Identifier tag.
In this case we change from listing "LICENSE-A LICENSE-B" or "LICENSE-A
or LICENSE-B" or "(LICENSE-A OR LICENSE-B)" to "LICENSE-A OR LICENSE-B"
as per the Linux Kernel style document. Note that parenthesis are
allowed so when they were used before we continue to use them.

mii: miiphy register address width change

This patch is added for PHY whose register offset value exceeds 0xFF and
cannot be used with "unsigned char" datatype in miiphy_read, miiphy_write
and miiphy_register functions. Datatype of register offset is changed to
unsigned short instead of unsigned char so that offset value greater then
0xFF can be used.

Create PHY Lib for U-Boot

Extends the mii_dev structure to participate in a full-blown MDIO and
PHY driver scheme. The mii_dev structure and miiphy calls are modified
in such a way to allow the original mii command and miiphy
infrastructure to work as before, but also to support a new set of APIs
which allow (among other things) sharing of PHY driver code and 10G support

The mii command will continue to support normal PHY management functions
(Clause 22 of 802.3), but will not be changed to support 10G
(Clause 45).

The basic design is similar to PHY Lib from Linux, but simplified for
U-Boot's network and driver infrastructure.

We now have MDIO drivers and PHY drivers

An MDIO driver provides:
read
write
reset

A PHY driver provides:
(optionally): probe
config - initial setup, starting of auto-negotiation
startup - waiting for AN, and reading link state
shutdown - any cleanup needed

The ethernet drivers interact with the PHY Lib using these functions:
phy_connect()
phy_config()
phy_startup()
phy_shutdown()

Each PHY driver can be configured separately, or all at once using
config_phylib_all_drivers.h (added in the patch which adds the drivers)

We also provide generic drivers for Clause 22 (10/100/1000), and
Clause 45 (10G) PHYs.

We also implement phy_reset(), and call it in phy_connect(). Because
phy_reset() is essentially the same as miiphy_reset, but:
a) must support 10G PHYs, and
b) should use the phylib primitives,

we implement miiphy_reset, using phy_reset(), but only when
CONFIG_PHYLIB is set. Otherwise, we just use the old version. In this
way, we save on compile size, even if we don't manage to save code size.

Rewrite the miiphybb (Bit-banged MII bus driver) in order to support an arbitrary number of mii buses.

This feature is useful when your board uses different mii buses for different
phys and all (or a part) of these buses are implemented via bit-banging mode.

The driver requires that the following macros should be defined into the board
configuration file:

CONFIG_BITBANGMII - Enable the miiphybb driver
CONFIG_BITBANGMII_MULTI - Enable the multi bus support

If the CONFIG_BITBANGMII_MULTI is not defined, the board's config file needs
to define at least the following macros:

MII_INIT - Generic code to enable the MII bus (optional)
MDIO_DECLARE - Declaration needed to access to the MDIO pin (optional)
MDIO_ACTIVE - Activate the MDIO pin as out pin
MDIO_TRISTATE - Activate the MDIO pin as input/tristate pin
MDIO_READ - Read the MDIO pin
MDIO(v) - Write v on the MDIO pin
MDC_DECLARE - Declaration needed to access to the MDC pin (optional)
MDC(v) - Write v on the MDC pin

The previous macros make the driver compatible with the previous version
(that didn't support the multi-bus).

When the CONFIG_BITBANGMII_MULTI is also defined, the board code needs to fill
the bb_miiphy_buses[] array with a record for each required bus and declare
the bb_miiphy_buses_num variable with the number of mii buses.
The record (struct bb_miiphy_bus) has the following fields/callbacks (see
miiphy.h for details):

char name[] - The symbolic name that must be equal to the MII bus
registered name
int (*init)() - Initialization function called at startup time (just
before the Ethernet initialization)
int (*mdio_active)() - Activate the MDIO pin as output
int (*mdio_tristate)() - Activate the MDIO pin as input/tristate pin
int (*set_mdio)() - Write the MDIO pin
int (*get_mdio)() - Read the MDIO pin
int (*set_mdc)() - Write the MDC pin
int (*delay)() - Delay function
void *priv - Private data used by board specific code

The board code will look like:

struct bb_miiphy_bus bb_miiphy_buses[] = {
{ .name = miibus#1, .init = b1_init, .mdio_active = b1_mdio_active, ... },
{ .name = miibus#2, .init = b2_init, .mdio_active = b2_mdio_active, ... },

Now, various phy devices can be attached to each of these slots(mux).
The information about these devices is passed to OS via device tree.

SPDX: Convert all of our multiple license tags to Linux Kernel style

When U-Boot started using SPDX tags we were among the early adopters and
there weren't a lot of other examples to borrow from. So we picked the
area of the file that usually had a full license text and replaced it
with an appropriate SPDX-License-Identifier: entry. Since then, the
Linux Kernel has adopted SPDX tags and they place it as the very first
line in a file (except where shebangs are used, then it's second line)
and with slightly different comment styles than us.

In part due to community overlap, in part due to better tag visibility
and in part for other minor reasons, switch over to that style.

This commit changes all instances where we have multiple licenses (in
these cases, dual license) declared in the SPDX-License-Identifier tag.
In this case we change from listing "LICENSE-A LICENSE-B" or "LICENSE-A
or LICENSE-B" or "(LICENSE-A OR LICENSE-B)" to "LICENSE-A OR LICENSE-B"
as per the Linux Kernel style document. Note that parenthesis are
allowed so when they were used before we continue to use them.

"miiphy_duplex()". It also adds function "miiphy_is_1000base_x ()", which
returns non-zero iff the PHY registers are configured for 1000BASE-X. The
"mii info" command is modified to distinguish between 1000BASE-T and -X.

SPDX: Convert all of our multiple license tags to Linux Kernel style

When U-Boot started using SPDX tags we were among the early adopters and
there weren't a lot of other examples to borrow from. So we picked the
area of the file that usually had a full license text and replaced it
with an appropriate SPDX-License-Identifier: entry. Since then, the
Linux Kernel has adopted SPDX tags and they place it as the very first
line in a file (except where shebangs are used, then it's second line)
and with slightly different comment styles than us.

In part due to community overlap, in part due to better tag visibility
and in part for other minor reasons, switch over to that style.

This commit changes all instances where we have multiple licenses (in
these cases, dual license) declared in the SPDX-License-Identifier tag.
In this case we change from listing "LICENSE-A LICENSE-B" or "LICENSE-A
or LICENSE-B" or "(LICENSE-A OR LICENSE-B)" to "LICENSE-A OR LICENSE-B"
as per the Linux Kernel style document. Note that parenthesis are
allowed so when they were used before we continue to use them.

Create PHY Lib for U-Boot

Extends the mii_dev structure to participate in a full-blown MDIO and
PHY driver scheme. The mii_dev structure and miiphy calls are modified
in such a way to allow the original mii command and miiphy
infrastructure to work as before, but also to support a new set of APIs
which allow (among other things) sharing of PHY driver code and 10G support

The mii command will continue to support normal PHY management functions
(Clause 22 of 802.3), but will not be changed to support 10G
(Clause 45).

The basic design is similar to PHY Lib from Linux, but simplified for
U-Boot's network and driver infrastructure.

We now have MDIO drivers and PHY drivers

An MDIO driver provides:
read
write
reset

A PHY driver provides:
(optionally): probe
config - initial setup, starting of auto-negotiation
startup - waiting for AN, and reading link state
shutdown - any cleanup needed

The ethernet drivers interact with the PHY Lib using these functions:
phy_connect()
phy_config()
phy_startup()
phy_shutdown()

Each PHY driver can be configured separately, or all at once using
config_phylib_all_drivers.h (added in the patch which adds the drivers)

We also provide generic drivers for Clause 22 (10/100/1000), and
Clause 45 (10G) PHYs.

We also implement phy_reset(), and call it in phy_connect(). Because
phy_reset() is essentially the same as miiphy_reset, but:
a) must support 10G PHYs, and
b) should use the phylib primitives,

we implement miiphy_reset, using phy_reset(), but only when
CONFIG_PHYLIB is set. Otherwise, we just use the old version. In this
way, we save on compile size, even if we don't manage to save code size.

Rewrite the miiphybb (Bit-banged MII bus driver) in order to support an arbitrary number of mii buses.

This feature is useful when your board uses different mii buses for different
phys and all (or a part) of these buses are implemented via bit-banging mode.

The driver requires that the following macros should be defined into the board
configuration file:

CONFIG_BITBANGMII - Enable the miiphybb driver
CONFIG_BITBANGMII_MULTI - Enable the multi bus support

If the CONFIG_BITBANGMII_MULTI is not defined, the board's config file needs
to define at least the following macros:

MII_INIT - Generic code to enable the MII bus (optional)
MDIO_DECLARE - Declaration needed to access to the MDIO pin (optional)
MDIO_ACTIVE - Activate the MDIO pin as out pin
MDIO_TRISTATE - Activate the MDIO pin as input/tristate pin
MDIO_READ - Read the MDIO pin
MDIO(v) - Write v on the MDIO pin
MDC_DECLARE - Declaration needed to access to the MDC pin (optional)
MDC(v) - Write v on the MDC pin

The previous macros make the driver compatible with the previous version
(that didn't support the multi-bus).

When the CONFIG_BITBANGMII_MULTI is also defined, the board code needs to fill
the bb_miiphy_buses[] array with a record for each required bus and declare
the bb_miiphy_buses_num variable with the number of mii buses.
The record (struct bb_miiphy_bus) has the following fields/callbacks (see
miiphy.h for details):

char name[] - The symbolic name that must be equal to the MII bus
registered name
int (*init)() - Initialization function called at startup time (just
before the Ethernet initialization)
int (*mdio_active)() - Activate the MDIO pin as output
int (*mdio_tristate)() - Activate the MDIO pin as input/tristate pin
int (*set_mdio)() - Write the MDIO pin
int (*get_mdio)() - Read the MDIO pin
int (*set_mdc)() - Write the MDC pin
int (*delay)() - Delay function
void *priv - Private data used by board specific code

The board code will look like:

struct bb_miiphy_bus bb_miiphy_buses[] = {
{ .name = miibus#1, .init = b1_init, .mdio_active = b1_mdio_active, ... },
{ .name = miibus#2, .init = b2_init, .mdio_active = b2_mdio_active, ... },
...
int bb_miiphy_buses_num = sizeof(bb_miiphy_buses) /
sizeof(bb_miiphy_buses[0]);

IBM OpenBIOS source code originally provided with some of the older PowerPC
4xx development boards. As a result, the original license of this code has

IBM is dual-licensing the IBM code contributions already present in U-Boot

Create PHY Lib for U-Boot

Extends the mii_dev structure to participate in a full-blown MDIO and
PHY driver scheme. The mii_dev structure and miiphy calls are modified
in such a way to allow the original mii command and miiphy
infrastructure to work as before, but also to support a new set of APIs
which allow (among other things) sharing of PHY driver code and 10G support

The mii command will continue to support normal PHY management functions
(Clause 22 of 802.3), but will not be changed to support 10G
(Clause 45).

The basic design is similar to PHY Lib from Linux, but simplified for
U-Boot's network and driver infrastructure.

We now have MDIO drivers and PHY drivers

An MDIO driver provides:
read
write
reset

A PHY driver provides:
(optionally): probe
config - initial setup, starting of auto-negotiation
startup - waiting for AN, and reading link state
shutdown - any cleanup needed

The ethernet drivers interact with the PHY Lib using these functions:
phy_connect()
phy_config()
phy_startup()
phy_shutdown()

Each PHY driver can be configured separately, or all at once using
config_phylib_all_drivers.h (added in the patch which adds the drivers)

We also provide generic drivers for Clause 22 (10/100/1000), and
Clause 45 (10G) PHYs.

We also implement phy_reset(), and call it in phy_connect(). Because
phy_reset() is essentially the same as miiphy_reset, but:
a) must support 10G PHYs, and
b) should use the phylib primitives,

we implement miiphy_reset, using phy_reset(), but only when
CONFIG_PHYLIB is set. Otherwise, we just use the old version. In this
way, we save on compile size, even if we don't manage to save code size.

Rewrite the miiphybb (Bit-banged MII bus driver) in order to support an arbitrary number of mii buses.

This feature is useful when your board uses different mii buses for different
phys and all (or a part) of these buses are implemented via bit-banging mode.

The driver requires that the following macros should be defined into the board
configuration file:

CONFIG_BITBANGMII - Enable the miiphybb driver
CONFIG_BITBANGMII_MULTI - Enable the multi bus support

If the CONFIG_BITBANGMII_MULTI is not defined, the board's config file needs
to define at least the following macros:

MII_INIT - Generic code to enable the MII bus (optional)
MDIO_DECLARE - Declaration needed to access to the MDIO pin (optional)
MDIO_ACTIVE - Activate the MDIO pin as out pin
MDIO_TRISTATE - Activate the MDIO pin as input/tristate pin
MDIO_READ - Read the MDIO pin
MDIO(v) - Write v on the MDIO pin
MDC_DECLARE - Declaration needed to access to the MDC pin (optional)
MDC(v) - Write v on the MDC pin

The previous macros make the driver compatible with the previous version
(that didn't support the multi-bus).

When the CONFIG_BITBANGMII_MULTI is also defined, the board code needs to fill
the bb_miiphy_buses[] array with a record for each required bus and declare
the bb_miiphy_buses_num variable with the number of mii buses.
The record (struct bb_miiphy_bus) has the following fields/callbacks (see
miiphy.h for details):

char name[] - The symbolic name that must be equal to the MII bus
registered name
int (*init)() - Initialization function called at startup time (just
before the Ethernet initialization)
int (*mdio_active)() - Activate the MDIO pin as output
int (*mdio_tristate)() - Activate the MDIO pin as input/tristate pin
int (*set_mdio)() - Write the MDIO pin
int (*get_mdio)() - Read the MDIO pin
int (*set_mdc)() - Write the MDC pin
int (*delay)() - Delay function
void *priv - Private data used by board specific code

The board code will look like:

struct bb_miiphy_bus bb_miiphy_buses[] = {
{ .name = miibus#1, .init = b1_init, .mdio_active = b1_mdio_active, ... },
{ .name = miibus#2, .init = b2_init, .mdio_active = b2_mdio_active, ... },
...
int bb_miiphy_buses_num = sizeof(bb_miiphy_buses) /
sizeof(bb_miiphy_buses[0]);

It was brought to our attention that U-Boot contains code derived from the
IBM OpenBIOS source code originally provided with some of the older PowerPC
4xx development boards. As a result, the original license of this code has
been carried in the various files for a number of years in the U-Boot project.

IBM is dual-licensing the IBM code contributions already present in U-Boot

miiphy: Add function to retrieve MDIO bus list head

In upcoming freescale board LX2160AQDS, the MDIO bus is muxed.
i.e. same MDIO bus can be routed to eight different slots depending
on mux register settings.

To support this mdio mux behavior, we add each MDIO bus mux as a
separate MDIO bus.

Now, various phy devices can be attached to each of these slots(mux).
The information about these devices is passed to OS via device tree.

To do the fdt fixups related to MDIO bus, its necessary that MDIO bus
list is accessed.Therefore, add a function to retrieve the list head.

SPDX: Convert all of our multiple license tags to Linux Kernel style

When U-Boot started using SPDX tags we were among the early adopters and
there weren't a lot of other examples to borrow from. So we picked the
area of the file that usually had a full license text and replaced it
with an appropriate SPDX-License-Identifier: entry. Since then, the
Linux Kernel has adopted SPDX tags and they place it as the very first
line in a file (except where shebangs are used, then it's second line)
and with slightly different comment styles than us.

In part due to community overlap, in part due to better tag visibility
and in part for other minor reasons, switch over to that style.

This commit changes all instances where we have multiple licenses (in
these cases, dual license) declared in the SPDX-License-Identifier tag.
In this case we change from listing "LICENSE-A LICENSE-B" or "LICENSE-A
or LICENSE-B" or "(LICENSE-A OR LICENSE-B)" to "LICENSE-A OR LICENSE-B"
as per the Linux Kernel style document. Note that parenthesis are
allowed so when they were used before we continue to use them.

config_phylib_all_drivers.h (added in the patch which adds the drivers)

We also provide generic drivers for Clause 22 (10/100/1000), and
Clause 45 (10G) PHYs.

We also implement phy_reset(), and call it in phy_connect(). Because
phy_reset() is essentially the same as miiphy_reset, but:
a) must support 10G PHYs, and
b) should use the phylib primitives,

we implement miiphy_reset, using phy_reset(), but only when
CONFIG_PHYLIB is set. Otherwise, we just use the old version. In this
way, we save on compile size, even if we don't manage to save code size.

Rewrite the miiphybb (Bit-banged MII bus driver) in order to support an arbitrary number of mii buses.

This feature is useful when your board uses different mii buses for different
phys and all (or a part) of these buses are implemented via bit-banging mode.

The driver requires that the following macros should be defined into the board
configuration file:

CONFIG_BITBANGMII - Enable the miiphybb driver
CONFIG_BITBANGMII_MULTI - Enable the multi bus support

If the CONFIG_BITBANGMII_MULTI is not defined, the board's config file needs
to define at least the following macros:

MII_INIT - Generic code to enable the MII bus (optional)
MDIO_DECLARE - Declaration needed to access to the MDIO pin (optional)
MDIO_ACTIVE - Activate the MDIO pin as out pin
MDIO_TRISTATE - Activate the MDIO pin as input/tristate pin
MDIO_READ - Read the MDIO pin
MDIO(v) - Write v on the MDIO pin
MDC_DECLARE - Declaration needed to access to the MDC pin (optional)
MDC(v) - Write v on the MDC pin

The previous macros make the driver compatible with the previous version
(that didn't support the multi-bus).

When the CONFIG_BITBANGMII_MULTI is also defined, the board code needs to fill
the bb_miiphy_buses[] array with a record for each required bus and declare
the bb_miiphy_buses_num variable with the number of mii buses.
The record (struct bb_miiphy_bus) has the following fields/callbacks (see
miiphy.h for details):

char name[] - The symbolic name that must be equal to the MII bus
registered name
int (*init)() - Initialization function called at startup time (just
before the Ethernet initialization)
int (*mdio_active)() - Activate the MDIO pin as output
int (*mdio_tristate)() - Activate the MDIO pin as input/tristate pin
int (*set_mdio)() - Write the MDIO pin
int (*get_mdio)() - Read the MDIO pin
int (*set_mdc)() - Write the MDC pin
int (*delay)() - Delay function
void *priv - Private data used by board specific code

The board code will look like:

struct bb_miiphy_bus bb_miiphy_buses[] = {
{ .name = miibus#1, .init = b1_init, .mdio_active = b1_mdio_active, ... },
{ .name = miibus#2, .init = b2_init, .mdio_active = b2_mdio_active, ... },
...
int bb_miiphy_buses_num = sizeof(bb_miiphy_buses) /
sizeof(bb_miiphy_buses[0]);

Dual-license IBM code contributions

It was brought to our attention that U-Boot contains code derived from the
IBM OpenBIOS source code originally provided with some of the older PowerPC
4xx development boards. As a result, the original license of this code has
been carried in the various files for a number of years in the U-Boot project.

IBM is dual-licensing the IBM code contributions already present in U-Boot
under either the terms of the GNU General Public License version 2, or the
original code license already present.

Initial revision

net: add MDIO_MUX DM class

Adds a class for MDIO MUXes, which control access to a series of
downstream child MDIOs.
MDIO MUX drivers are required to implement a select function used to switch
between child buses.
MUX children are registered as MDIO buses and they can be used just like
regular MDIOs.

miiphy: Add function to retrieve MDIO bus list head

In upcoming freescale board LX2160AQDS, the MDIO bus is muxed.
i.e. same MDIO bus can be routed to eight different slots depending
on mux register settings.

To support this mdio mux behavior, we add each MDIO bus mux as a
separate MDIO bus.

Now, various phy devices can be attached to each of these slots(mux).
The information about these devices is passed to OS via device tree.

To do the fdt fixups related to MDIO bus, its necessary that MDIO bus
list is accessed.Therefore, add a function to retrieve the list head.

SPDX: Convert all of our multiple license tags to Linux Kernel style

When U-Boot started using SPDX tags we were among the early adopters and
there weren't a lot of other examples to borrow from. So we picked the
area of the file that usually had a full license text and replaced it
with an appropriate SPDX-License-Identifier: entry. Since then, the
Linux Kernel has adopted SPDX tags and they place it as the very first
line in a file (except where shebangs are used, then it's second line)
and with slightly different comment styles than us.

In part due to community overlap, in part due to better tag visibility
and in part for other minor reasons, switch over to that style.

This commit changes all instances where we have multiple licenses (in
these cases, dual license) declared in the SPDX-License-Identifier tag.
In this case we change from listing "LICENSE-A LICENSE-B" or "LICENSE-A
or LICENSE-B" or "(LICENSE-A OR LICENSE-B)" to "LICENSE-A OR LICENSE-B"
as per the Linux Kernel style document. Note that parenthesis are
allowed so when they were used before we continue to use them.
