83d290c56f 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.

e7c831543a clk: at91: utmi: Set the reference clock frequency
By default, it is assumed that the UTMI clock is generated from
a 12 MHz reference clock (MAINCK). If it's not the case, the FREQ
field of the SFR_UTMICKTRIM has to be updated to generate the UTMI
clock in the proper way.

The UTMI clock has a fixed rate of 480 MHz. In fact, there is no
multiplier we can configure. The multiplier is managed internally,
depending on the reference clock frequency, to achieve the target
of 480 MHz.

The patch is cloned from the patch of mailing-list:
	[PATCH v2] clk: at91: utmi: set the mainck rate

f7cf291aa7 ARM: at91: sama5d2: configure the L2 cache memory
The SAMA5D2 has a second internal SRAM that can be reassigned as a L2
cache memory.
Make sure it is configured as a L2 cache memory when booting from a SPL
image.

Based on the commit b5ea95ef2b5b from the at91bootstrap repository.

e4677f1ae2 arm: at91/spl: atmel_sfr: move saic redirect to separate file
To make saic redirect code sharing with other SoCs, move the
saic redirect code from SAMA5D4 particular file,
mach-at91/armv7/sama5d4_devices.c to a separate file,
mach-at91/atmel_sfr.c

Move ATMEL_SFR_AICREDIR_KEY definition to sama5d4.h, because each
SoC has its own value.
