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. Signed-off-by: Tom Rini <trini@konsulko.com>

ARM: atmel: at91sam9m10g45ek: enable spl support Supports boot up from NAND flash with software ECC eanbled. And supports boot up from SD/MMC card with FAT file system. As the boot from SD/MMC card with FAT file system, the BSS segment is too big to fit into SRAM, so, use the lds to put it into SDRAM. Signed-off-by: Bo Shen <voice.shen@atmel.com>

spl: arm: Make sure to include all of the u_boot_list entries Starting with 96e5b03 we use a linker list for partition table information. However since we use this in SPL we need to make sure that the SPL linker scripts include these as well. While doing this, it's best to simply include all linker lists to future proof ourselves.

ARM: at91: lds: add test for SPL binary size and bss size Add test for the SPL binary size and the bss section size. This will throw an error at build time if the SPL sections do not fit in the designated RAM area, thus avoiding oversizing the SPL. Based on original work by Wenyou Yang.
