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: add relocation support !! This breaks support for all arm boards !! To compile in old style, you must define CONFIG_SYS_ARM_WITHOUT_RELOC or you can compile with "CONFIG_SYS_ARM_WITHOUT_RELOC=1 ./MAKEALL board" !! This define will be removed soon, so convert your board to use relocation support Portions of this work were supported by funding from the CE Linux Forum.

arm: Move CP15 init out of cpu_init_crit() Some SOCs have do not start up with their 'main' CPU. The first U-Boot code may then be executed with a CPU which does not have a CP15, or not a useful one. Here we split the initialization of CP15 into a separate call, which can be performed later if required. Once the main CPU is running, you should call cpu_init_cp15() to perform this init as early as possible. Existing ARMv7 boards which define CONFIG_SKIP_LOWLEVEL_INIT should not need to change, this CP15 init is still skipped in that case. The only impact for these boards is that the cpu_init_cp15() will be available even if it is never used on these boards.
