This is the same migration path as commit b6251db8c3f0 ("Kconfig:

I also moved the description in README to the Kconfig help.
I ripped off the sentence about 'LWMON' since it is gone already.

I only let my boards migrate, leaving the rest to platform maintainers.

ARM: uniphier: do not modify bootcmd environment variable at run-time

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'.

With the migration to distro-boot, the size of the U-Boot proper
image for uniphier_v7_defconfig exceeded the current limit, 576KB.
Increase it to 832KB.

CONFIG_SYS_UBOOT_BASE must be moved as well to avoid the image
over-wrap because the boot ROM of Pro4, Pro5, PXs2/LD6b loads
the SPL to the physical address 0x100000.

ARM: uniphier: enable distro boot

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.

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.

ARM: uniphier: move SPL stack address

Currently, the address region, 0xf8000 - 0x100000, is used for SPL
stack for the 32bit SoCs. Because the U-Boot proper image starts
from 0x70000, the maximum size of the U-Boot proper image is 544KB
(0x70000 - 0xf8000) for the NOR boot mode. Now uniphier_v7_defconfig
is almost hitting this size limit. Changing CONFIG_SPL_STACK can
raise the size limit with less impact. With this, the size limit
will increase to 576KB (0x70000 - 0x100000). If we need to increase
it even more, we would be able to change CONFIG_SYS_UBOOT_BASE at the
cost of the flashing command changes.

ARM: uniphier: select a correct mmc device before flashing images

Some boards support an SD card and an eMMC device at the same time.
Since both belong to 'mmc', they are identified by a device number.
When the device number of the eMMC is 1 instead 0, "mmc dev" command
must be performed to switch the target device before flashing images.

Convert all of CONFIG_CONS_INDEX to Kconfig

This converts the following to Kconfig:
CONFIG_CONS_INDEX

We have existing entries for this option in a number of places, with
different guards on them. They're also sometimes used for things not
directly inside of the serial driver. First, introduce a new symbol to
guard the use of CONFIG_CONS_INDEX, so that in the case where we don't
need this for the serial driver, but for some other use, we can still do
it. Next, consolidate all of these into the single entry in
drivers/serial/Kconfig. Finally, introduce CONS_INDEX_[023456] so that
we can imply a correct value here to make the defconfig side of this
smaller.
