SPDX: Convert all of our single 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 a single declared
license in the tag as both the before and after are identical in tag
contents. There's also a few places where I found we did not have a tag
and have introduced one.

omap-common: Common boot code OMAP3 support and cleanup

This introduces OMAP3 support for the common omap boot code, as well as a
major cleanup of the common omap boot code.

First, the omap_boot_parameters structure becomes platform-specific, since its
definition differs a bit across omap platforms. The offsets are removed as well
since it is U-Boot's coding style to use structures for mapping such kind of
data (in the sense that it is similar to registers). It is correct to assume
that romcode structure encoding is the same as U-Boot, given the description
of these structures in the TRMs.

The original address provided by the bootrom is passed to the U-Boot binary
instead of a duplicate of the structure stored in global data. This allows to
have only the relevant (boot device and mode) information stored in global data.
It is also expected that the address where the bootrom stores that information
is not overridden by the U-Boot SPL or U-Boot.

The save_omap_boot_params is expected to handle all special cases where the data
provided by the bootrom cannot be used as-is, so that spl_boot_device and
spl_boot_mode only return the data from global data.

All of this is only relevant when the U-Boot SPL is used. In cases it is not,
save_boot_params should fallback to its weak (or board-specific) definition.
save_omap_boot_params should not be called in that context either.

am335x_evm: am33xx_spl_board_init function and scale core frequency

Add a am33xx_spl_board_init (and enable the PMICs) that we may see,
depending on the board we are running on. In all cases, we see if we
can rely on the efuse_sma register to tell us the maximum speed. In the
case of Beaglebone White, we need to make sure we are on AC power, and
are on later than rev A1, and then we can ramp up to the PG1.0 maximum
of 720Mhz. In the case of Beaglebone Black, we are either on PG2.0 that
supports 1GHz or PG2.1. As PG2.0 may or may not have efuse_sma set, we
cannot rely on this probe. In the case of the GP EVM, EVM SK and IDK we
need to rely on the efuse_sma if we are on PG2.1, and the defaults for

SPDX: Convert all of our single 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 a single declared
license in the tag as both the before and after are identical in tag
contents. There's also a few places where I found we did not have a tag
and have introduced one.

omap-common: Common boot code OMAP3 support and cleanup

This introduces OMAP3 support for the common omap boot code, as well as a
major cleanup of the common omap boot code.

First, the omap_boot_parameters structure becomes platform-specific, since its
definition differs a bit across omap platforms. The offsets are removed as well
since it is U-Boot's coding style to use structures for mapping such kind of
data (in the sense that it is similar to registers). It is correct to assume
that romcode structure encoding is the same as U-Boot, given the description
of these structures in the TRMs.

The original address provided by the bootrom is passed to the U-Boot binary
instead of a duplicate of the structure stored in global data. This allows to
have only the relevant (boot device and mode) information stored in global data.
It is also expected that the address where the bootrom stores that information
is not overridden by the U-Boot SPL or U-Boot.

The save_omap_boot_params is expected to handle all special cases where the data
provided by the bootrom cannot be used as-is, so that spl_boot_device and
spl_boot_mode only return the data from global data.

All of this is only relevant when the U-Boot SPL is used. In cases it is not,
save_boot_params should fallback to its weak (or board-specific) definition.
save_omap_boot_params should not be called in that context either.

am335x_evm: am33xx_spl_board_init function and scale core frequency

Add a am33xx_spl_board_init (and enable the PMICs) that we may see,
depending on the board we are running on. In all cases, we see if we
can rely on the efuse_sma register to tell us the maximum speed. In the
case of Beaglebone White, we need to make sure we are on AC power, and
are on later than rev A1, and then we can ramp up to the PG1.0 maximum
of 720Mhz. In the case of Beaglebone Black, we are either on PG2.0 that
supports 1GHz or PG2.1. As PG2.0 may or may not have efuse_sma set, we
cannot rely on this probe. In the case of the GP EVM, EVM SK and IDK we
need to rely on the efuse_sma if we are on PG2.1, and the defaults for
PG1.0/2.0.
