Some users might want to modify 'bootcmd' at compile-time by editing
include/configs/uniphier.h, but overwriting it at run-time makes it
impossible.
Instead, set 'bootdev' at run-time, which contains the boot device the
system is booting from, then indirectly reference it from 'bootcmd'.
It is up to users whether to override 'bootcmd'.

Switch to the distro boot for UniPhier platform.
- Remove the environment vairalbes used to load images from raw
block devices.
- Keep the command to download images via tftp. This will be
useful to boot the kernel when no valid kernel image is ready
yet in the file system.
- Use root.cpio.gz instead of root.cpio.uboot because we always know
the file size of the init ramdisk; it is loaded via either a file
system or network.
- Rename fit_addr_r to kernel_addr_r, which the distro command
checks to get the load address of FIT image.

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.

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.

LD20 / PXs3 boards are equipped with a large amount of memory beyond
the 32 bit address range. U-Boot relocates itself to the end of the
available RAM.
This is a problem for DMA engines that only support 32 bit physical
address, like the SDMA of SDHCI controllers.
In fact, U-Boot does not need to run at the very end of RAM. It is
rather troublesome for drivers with DMA engines because U-Boot does
not have API like dma_set_mask(), so DMA silently fails, making the
driver debugging difficult.
Hide the memory region that exceeds the 32 bit address range. It can
be done by simply carving out gd->ram_size. It would also possible to
override get_effective_memsize() or to define CONFIG_MAX_MEM_MAPPED,
but dram_init() is a good enough place to do this job.

UniPhier 32-bit SoCs use CONFIG_SPL_OF_CONTROL. So, many nodes must
be marked as dm-pre-reloc to prevent fdtgrep from stripping them off.
Sprinkling U-Boot-specific properties all over the place is painful
because DT files are synced with Linux from time to time.
Split u-boot,dm-pre-reloc out to uniphier-v7-u-boot.dtsi, which is
appended to UniPhier V7 DTS before the build.

When we import code from Linux, with regular re-sync planned, we want
to use printk() and pr_*(). U-Boot does not support them in a clean
way. So, people end up with local macros, or compat headers here and
there, then we occasionally see build errors of definition conflicts.
We have include/linux/compat.h, but putting all sorts of unrelated
things into a single header is just a temporal workaround. Hence this
patch, to find the best home for all printk variants. If you want to
use printk() and friends, please include <linux/printk.h>. This header
is self-contained, and pulls in only a few headers.
When I was testing this clean-up, I noticed the image size exceeded
its platform limit on some boards. This is because all pr_*() that
were previously defined as no-op in include/linux/mtd/mtd.h (unless
CONFIG_MTD_DEBUG is set), are now enabled.
To make such boards happy, this commit also implements CONFIG_LOGLEVEL.
The concept is similar to the kernel parameter "loglevel". (Actually,
the Kconfig help message was taken from kernel-paremeter.txt of Linux)
Messages with a loglevel smaller than console loglevel will be printed.
The difference is the loglevel is build-time determined. To save the
image size, lower priority pr_*() are compiled out. I set the default
of CONFIG_LOGLEVEL to 6, i.e. pr_notice and higher priority messages
are compiled in.
I adjusted CONFIG_LOGLEVEL to avoid build error for some boards.
