Revert "Merge patch series "arm: dts: am62-beagleplay: Fix Beagleplay Ethernet""

When bringing in the series 'arm: dts: am62-beagleplay: Fix Beagleplay
Ethernet"' I failed to notice that b4 noticed it was based on next and
so took that as the base commit and merged that part of next to master.

This reverts commit c8ffd1356d42223cbb8c86280a083cc3c93e6426, reversing
changes made to 2ee6f3a5f7550de3599faef9704e166e5dcace35.

treewide: convert bd_t to struct bd_info by coccinelle

The Linux coding style guide (Documentation/process/coding-style.rst)
clearly says:

It's a **mistake** to use typedef for structures and pointers.

Besides, using typedef for structures is annoying when you try to make
headers self-contained.

Let's say you have the following function declaration in a header:

void foo(bd_t *bd);

This is not self-contained since bd_t is not defined.

To tell the compiler what 'bd_t' is, you need to include <asm/u-boot.h>

#include <asm/u-boot.h>
void foo(bd_t *bd);

Then, the include direcective pulls in more bloat needlessly.

If you use 'struct bd_info' instead, it is enough to put a forward
declaration as follows:

struct bd_info;
void foo(struct bd_info *bd);

Right, typedef'ing bd_t is a mistake.

I used coccinelle to generate this commit.

The semantic patch that makes this change is as follows:

net: rtl8139: Fill in SPDX tag

The rtl8139 driver is derived from Etherboot driver, which is in
turn derived from Linux 8139too driver added in Linux 2.2.18pre14.
An undocumented change in Linux 2.4.10.2 added a new field to the
driver, MODULE_LICENSE("GPL"); . According to current Linux kernel
licensing rules, Documentation/process/license-rules.rst, quote:

"GPL" Module is licensed under GPL version 2. This
does not express any distinction between
GPL-2.0-only or GPL-2.0-or-later. The exact
license information can only be determined
via the license information in the
corresponding source files.

And since the code does not contain any "future" clause, the tag
is therefore GPL-2.0 only.

net: rtl8139: Fill in SPDX tag

The rtl8139 driver is derived from Etherboot driver, which is in
turn derived from Linux 8139too driver added in Linux 2.2.18pre14.
An undocumented change in Linux 2.4.10.2 added a new field to the
driver, MODULE_LICENSE("GPL"); . According to current Linux kernel
licensing rules, Documentation/process/license-rules.rst, quote:

"GPL" Module is licensed under GPL version 2. This
does not express any distinction between
GPL-2.0-only or GPL-2.0-or-later. The exact
license information can only be determined
via the license information in the
corresponding source files.

And since the code does not contain any "future" clause, the tag
is therefore GPL-2.0 only.

treewide: convert bd_t to struct bd_info by coccinelle

The Linux coding style guide (Documentation/process/coding-style.rst)
clearly says:

It's a **mistake** to use typedef for structures and pointers.

Besides, using typedef for structures is annoying when you try to make
headers self-contained.

Let's say you have the following function declaration in a header:

void foo(bd_t *bd);

This is not self-contained since bd_t is not defined.

To tell the compiler what 'bd_t' is, you need to include <asm/u-boot.h>

#include <asm/u-boot.h>
void foo(bd_t *bd);

Then, the include direcective pulls in more bloat needlessly.

If you use 'struct bd_info' instead, it is enough to put a forward
declaration as follows:

struct bd_info;
void foo(struct bd_info *bd);

Right, typedef'ing bd_t is a mistake.

I used coccinelle to generate this commit.

The semantic patch that makes this change is as follows:

<smpl>

typedef bd_t;

-bd_t
+struct bd_info

An undocumented change in Linux 2.4.10.2 added a new field to the

licensing rules, Documentation/process/license-rules.rst, quote:

"GPL" Module is licensed under GPL version 2. This
does not express any distinction between
GPL-2.0-only or GPL-2.0-or-later. The exact
license information can only be determined

treewide: convert bd_t to struct bd_info by coccinelle

The Linux coding style guide (Documentation/process/coding-style.rst)
clearly says:

It's a **mistake** to use typedef for structures and pointers.

Besides, using typedef for structures is annoying when you try to make
headers self-contained.

Let's say you have the following function declaration in a header:

void foo(bd_t *bd);

This is not self-contained since bd_t is not defined.

To tell the compiler what 'bd_t' is, you need to include <asm/u-boot.h>

#include <asm/u-boot.h>
void foo(bd_t *bd);

Then, the include direcective pulls in more bloat needlessly.

If you use 'struct bd_info' instead, it is enough to put a forward
declaration as follows:

struct bd_info;
void foo(struct bd_info *bd);

Right, typedef'ing bd_t is a mistake.

I used coccinelle to generate this commit.

The semantic patch that makes this change is as follows:

<smpl>
@@
typedef bd_t;
@@
-bd_t
+struct bd_info

net: Fix mcast function pointer prototype

This fixes the following compiler warnings when activating
CONFIG_MCAST_TFTP:

tsec.c: In function 'tsec_mcast_addr':
tsec.c:130:2: warning: passing argument 2 of 'ether_crc' makes pointer
from integer without a cast [enabled by default]
In file included from /work/u-boot-net/include/common.h:874:0,
from tsec.c:15:
/work/u-boot-net/include/net.h:189:5: note: expected 'const unsigned
char *' but argument is of type 'u8'
tsec.c: In function 'tsec_initialize':
tsec.c:646:13: warning: assignment from incompatible pointer type
[enabled by default]
eth.c: In function 'eth_mcast_join':
eth.c:358:2: warning: passing argument 2 of 'eth_current->mcast' makes
integer from pointer without a cast [enabled by default]
eth.c:358:2: note: expected 'u32' but argument is of type 'u8 *'

In the eth_mcast_join() implementation, eth_current->mcast()
takes a u8 pointer to the multicast mac address and not a ip
address value as implied by its prototype.

Fix parameter type mismatch for tsec_macst_addr() (tsec.c):
ether_crc() takes a u8 pointer not a u8 value.
mcast() is given a u8 pointer to the multicats mac address.
Update parameter type for the rest of mcast() instances.

net: rtl8139: Fill in SPDX tag

The rtl8139 driver is derived from Etherboot driver, which is in
turn derived from Linux 8139too driver added in Linux 2.2.18pre14.
An undocumented change in Linux 2.4.10.2 added a new field to the
driver, MODULE_LICENSE("GPL"); . According to current Linux kernel
licensing rules, Documentation/process/license-rules.rst, quote:

"GPL" Module is licensed under GPL version 2. This
does not express any distinction between
GPL-2.0-only or GPL-2.0-or-later. The exact
license information can only be determined
via the license information in the
corresponding source files.

And since the code does not contain any "future" clause, the tag
is therefore GPL-2.0 only.
