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.

AT91 ma5d4evk board uses atmel spi driver, enable DM_SPI to
use dm functionality.
Kept few functions related to non-dm and gpio on board
files for reference and will be remove once code moved
to relevant drivers.

We are now using an env_ prefix for environment functions. Rename setenv()
for consistency. Also add function comments in common.h.

Discern the SoMs based on the presence of SPI flash to support both
variants of the SoM, one booting from SPI NOR and one booting from
eMMC.

Continue loading U-Boot from MMC2 when the SPL was loaded using SAM-BA
loader. This allows the board to boot system from the removable media
instead of the eMMC, which is useful for commissioning purposes. When
booting from the eMMC, always boot from it as it is not possible to
boot from the SD interface directly.

The SDHCI1 is the primary boot controller on rev. 2.1 SoM, which
is the version available on the market. Swap the controller order
to match this and future versions of the SoM.

Init the controllers, otherwise the board cannot boot from SD/MMC.
This boot option is new on rev. 2.1 SoM .

The CAN controllers need slight delay between toggling of their reset
line. Move this action into board_init(), otherwise timer will not be
initialized and the board might hang.

According to the datasheet, sequential mapping is used for DDR
SDRAM, while interleaved mapping is used for regular SDRAM.
Incorrect configuration of this bit does indeed cause sporadic
memory instability.
