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.

pxa: Fix boot hang by avoiding vector relocation Since commit 3ff46cc42b9d73d0 ("arm: relocate the exception vectors") pxa does not boot anymore. Add a specific relocate_vectors macro that skips the vector relocation, as the pxa SoC does not provide RAM at the high vectors address (0xFFFF0000), and (0x00000000) maps to ROM. This allows pxa to boot again. Cc: Marek Vasut <marex@denx.de> Signed-off-by: Andrew Ruder <andrew.ruder@elecsyscorp.com> 2015-08-12 17:55:47 +00:00			`/*`
