GPT Partition labels are used for determining the right
root filesystem to boot from.
The U-Boot environment is configured to reside in the eMMC hardware
boot partition we are currently booted from.
This should enable a dual copy approach for upgrading the bootloader.
One can overwrite the inactive hardware partition with new bootloader
and environment and afterwards switch the eMMC boot partition for an
atomic bootloader switch.

It doesn't seem appropriate for arch/SOC to use a board-level
functionality (CONFIG_OF_BOARD_FIXUP), because this prevents boards
that need to do FDT fixup from using that feature.
Also, this code is completely dead and useless (from comments by
Rasmus Villemoes on the mailing list):
- No in-tree imx8m-based board seems to set CONFIG_OF_BOARD_FIXUP
- The nodes which that function wants to disable don't even exist in
the U-Boot copy of imx8mp.dtsi.
This code was introduced in commit 35bb60787b. It seems to be some
random import of code from downstream NXP U-Boot, with a commit
message that makes no sense in upstream context.

At BDF address 00:00.0 is fictional device which PCI configuration header
is for configuring mpc85xx PCI controller itself. PCI config space of this
device has ATMU inbound registers on position of PCI BARs. Trying to do PCI
auto configuration of this device cause rewriting ATMU inbound registers.
To avoid it, do not allow overwriting registers at BARs positions. And
because this device does not have any PCI memory, return zeros when trying
to read PCI BARs config space registers. It signals to auto configuration
tool to not allocate any PCI memory for this device.

Please pull the second part of the sunxi pull request for this cycle.
Another bunch of patches that replace old-school U-Boot hacks with
proper DM based code, this time for the raw NAND flash driver, and the
USB PHY VBUS detection code. Plus two smaller patches that were sitting
in my inbox for a while.
Gitlab CI passed. In lack of some supported board with NAND flash I
couldn't really test this part, but apparently this was tested by the
reviewer. I briefly ran the branch on some boards with USB-OTG, and
this still worked.
This pull request adds support for the last CPU board from
CS GROUP France (previously CSSI).
That CPU board called CMPCPRO has a mpc8321E CPU (Family PQII PRO hence
its name) and can be plugged in place of the CMPC885 board.
In order to support that new board, the following changes are included
in this series:
- Make the mpc8xx watchdog driver more generic for reusing it
with mpc83xx
- Fix various small problems on mpc83xx platform
- Add a GPIO Driver for QE GPIOs
- Add support for mpc832x into mpc83xx SPI driver
- Refactor existing board code that will be shared with new board
- Add the new board

would be ensuring a bad dereference. Instead, looking at the function we
rework things so that when CONFIG_EXPO is not enabled (and so, no UI) we
