93565cc94c arm: mach-rmobile: Drop <common.h>
For most source files we can just drop <common.h>. We need to add an
include for <asm/u-boot.h> in a couple of places. Also sort the include
list in memmap-gen3.c while we're here.

dbada49554 arm: rmobile: Fix off-by-one error in cpuinfo
In rmobile_cpuinfo_idx() there is an off-by-one error in accessing the
rmobile_cpuinfo array.

At the end of the loop, i is equal to the array size, i.e.
rmobile_cpuinfo[i] accesses one entry past the end of the array. The
last entry in the array is a fallback value so the loop should count to
ARRAY_SIZE(rmobile_cpuinfo) - 1 instead, this will leave i equal to the
index of the fallback value if no match is found.

These functions belong in cpu_func.h. Another option would be cache.h
but that code uses driver model and we have not moved these cache
functions to use driver model. Since they are CPU-related it seems
reasonable to put them here.

e5cb6bd9a2 ARM: rmobile: Generate fitting mem_map on Gen3
Patch "ARM: rmobile: Mark 4-64GiB as DRAM on Gen3" marked the entire
64bit DRAM space as cachable. On CortexA57, this might result in odd
side effects, where the CPU tries to prefetch from those areas and if
there is no DRAM backing them, CPU bus hang can happen.

This patch fixes it by generating the mem_map structure based on the
actual memory layout obtained from the DT, thus not marking areas
without any DRAM behind them as cachable.

83d290c56f 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.
