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>

Add architecture-specific global data We plan to move architecture-specific data into a separate structure so that we can make the rest of it common. As a first step, create struct arch_global_data to hold these fields. Initially it is empty. This patch applies to all archs at once. I can split it if this is really a pain.

microblaze: cache: introduce cpuinfo structure Introduce a minimal cpuinfo structure to hold cache related info. The instruction/data cache size and cache line size are initialized early in the boot to default Kconfig values. They will be overwritten with data from PVR/dtb if the microblaze UCLASS_CPU driver is enabled. The cpuinfo struct was placed in global_data to allow the microblaze UCLASS_CPU driver to also run before relocation (initialized global data should be read-only before relocation). gd_cpuinfo() helper macro was added to avoid volatile "-Wdiscarded-qualifiers" warnings when using the pointer directly.
