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> 2018-05-06 21:58:06 +00:00			`# SPDX-License-Identifier: GPL-2.0+`

ARM: pxa: Fix OneNAND SPL builds The OneNAND SPL used on PXA is slightly obscure. Due to the OneNAND limitation, where we have only the first 1KiB of the OneNAND available upon power-up as a memory-mapped area, from which the CPU starts executing, we place only the most essential code into this first 1KiB . This code copies the rest of the SPL into SRAM and jumps to it. This code is stored in section .text.0 . The rest of the SPL is stored in section .text.1 . When running the OBJCOPY on the SPL, it will preserve only .text section, but the .text.0 and .text.1 are stripped away from the result, thus making the SPL binary empty. The patch adds additional -j parameters to the OBJCOPY for PXA during the SPL build, which will preserve the .text.0 and .text.1 sections. Moreover, this patch also adds missing functions into the .text.0 section, since otherwise the PXA270 with 1KiB-window OneNAND won't be able to boot.
