acf1500138 arm: v7: Kconfig: Rename CPU_V7 as CPU_V7A
Currently CPU_V7 kconfig symbol supports only ARMv7A architectures under
armv7 folder. This led to a misconception of creating separate folders
for armv7m and armv7r. There is no reason to create separate folder for
other armv7 based architectures when it can co-exist with few Kconfig
symbols.

As a first step towards a common folder, rename CPU_V7 as CPUV7A. Later
separate Kconfig symbols can be added for CPU_V7R and CPU_V7M and
can co exist in the same folder.

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.

95e74a3df7 arm: exynos7420: remove custome low level init function
Remove the custom low-level initialization function and reuse the
default low-level initialization function. But this requires the
ARMV8_MULTIENTRY config option to be enabled for Exynos7420.

On Exynos7420, the boot CPU belongs to the second cluster and so
with ARMV8_MULTIENTRY config option enabled, the 'branch_if_master'
macro fails to detect the CPU as boot CPU. As a temporary workaround
the CPU_RELEASE_ADDR is set to point to '_main'.

36aa893775 arm: exynos: realign the code to allow support for newer 64-bit platforms
The existing Exynos 32-bit platform support needs to be realigned in
order to support newer 64-bit Exynos platforms. The driver model will
be utlized for drivers on the 64-bit Exynos platforms and so some of
the older platform support code would not be required for the newer
64-bit Exynos platforms.
