* SPDX: Convert all of our single license tags to Linux Kernel styleTom Rini2018-05-071-2/+1
| | | | | | | | | | | | | | | | | | | | 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>

* m68k: cache: add an empty stub functions for invalidate/flush dcacheWu, Josh2015-08-121-0/+9
| | | | | | | | | | | | | | Since some driver like ohci, lcd used dcache functions. But m68k don't implement the invalidate_dcache_range()/flush_dcache_range() functions. To avoid compiling errors this patch adds an weak empty stub function for all m68k cpu. Also each cpu can implement its own implementation. If not implemented then by default is using an empty function. Signed-off-by: Josh Wu <josh.wu@atmel.com> Acked-by: Angelo Dureghello <angelo@sysam.it>

* Move lib_$ARCH directories to arch/$ARCH/libPeter Tyser2010-04-131-0/+150
Also move lib_$ARCH/config.mk to arch/$ARCH/config.mk This change is intended to clean up the top-level directory structure and more closely mimic Linux's directory organization. Signed-off-by: Peter Tyser <ptyser@xes-inc.com>
