Instead of hardcoding the watchdog for reset, and the PMIC for poweroff,
use the sysreset framework to manage the available poweroff/reset
backends. This allows (as examples) using the PMIC to do a cold reset,
and using a GPIO to power off H3/H5 boards lacking a PMIC. Furthermore,
it removes the need to hardcode watchdog MMIO addresses, since the
sysreset backends can be discovered using the device tree.

vexpress_ca9x4 is seemingly the only board except for qemu_arm which
is able to run U-Boot correctly, using the `-M vexpress-a9` option to
QEMU. Building for qemu_arm and running qemu-system-arm with the `-M
virt` argument has a number of downsides, most importantly that it
only supports virtio storage drivers. This significantly reduces its
usefulness in testing memory card and Flash solutions, especially when
the tested images are from a third party source.
So therefore we reintroduce the vexpress_ca9x4 board in this commit,
with the explicit goal of using it with QEMU.
A number of differences to note from the original:
* Since the board was apparently unmaintained, I have now set myself
as the maintainer.
* The board has been converted to use the driver model, which was the
reason it was removed in the first place.
* The vexpress_ca15_tc2 and vexpress_ca5x2 boards, which were removed
in the same commit, are not necessary for the QEMU use case, and
have been omitted.
* An `mmc0` alias was introduced in the dts file. The mmc is not
detected correctly without this, now that it's based on the device
tree instead of the board's init function.
* A couple of other nodes were removed because they were problematic
when trying to run the UEFI bootmgr. Once again, the primary use
case here is QEMU, and these nodes are not needed for that to work.
* Unnecessary board init code has been removed, thanks to driver model
and device tree.
* `CONFIG_OF_EMBED` has been enabled. I know this goes against
recommended practice, but there doesn't seem to be any other way to
pass the dtb to U-Boot in the QEMU scenario. Using the -dtb argument
does not work, I suppose because U-Boot doesn't use the same
mechanics as the kernel when it's booting.
* Load addresses have been changed to fit QEMU use case.
People wanting to get a more detailed, yet somewhat isolated, diff
between this and the original, can run this command:
git diff c6c26a05b89f25a06e7562f8c2071b60fd0c9eac~1 -- \

With the exceptions of ds109, ds414, icnova-a20-swac, nokia_rx51 and

support but never supported a kernel so old as to require it. Further,
some platforms are old enough to support both, but are well supported by
devicetree booting, and have been for a number of years. This is
because some of the ATAGs related functions have been re-used to provide
the same kind of information, but for devicetree or just generally to
inform the user. When needed still, rename these functions to
get_board_revision() instead, to avoid conflicts. In other cases, these
functions were simply unused, so drop them.

Per a request from Andre Przywara and agreed with by Peter Hoyes, the
vexpress aemv8r support wasn't quite ready to be merged, but the
discussion had moved off list. We should keep the first patch in the

commits:
e0bd6f31ce doc: Add documentation for the Arm vexpress board configs

The BASER_FVP board variant is implemented on top of the BASE_FVP board
config (which, in turn, is based on the Juno Versatile Express board
config). They all share a similar memory map - for BASER_FVP the map is
inverted from the BASE_FVP
(https://developer.arm.com/documentation/100964/1114/Base-Platform/Base---memory/BaseR-Platform-memory-map)
* Create new TARGET_VEXPRESS64_BASER_FVP target, which uses the same
board config as BASE_FVP and JUNO
* Adapt vexpress_aemv8a.h header file to support BASER_FVP (and rename
to vexpress_aemv8.h)
* Enable config to switch to EL1 for the BASER_FVP
* Create vexpress_aemv8r defconfig
* Provide an MPU memory map for the BASER_FVP
For now, only single core boot is supported.

A U-Boot image could be loaded and executed at a different
location than it was linked at.
For example, Aspeed takes a stable release version of U-Boot image
as the golden one for recovery purposes. When the primary storage
such as flash is corrupted, the golden image would be loaded to any
SRAM/DRAM address on demands through ethernet/UART/etc and run for
rescue.
To deal with this condition, the PIE is needed as there is only one
signed, golden image, which could be however executed at different
places.
This patch adds the PIE support for ARMv7 platform.

controller has now gone two years past the deadline, enforce migration.
This is done by:
- Ensuring that all host controller options (other than the very legacy
old MUSB ones) now select USB_HOST. USB_HOST now enforces DM_USB and
OF_CONTROL.
- Remove other parts of Kconfig logic that had platforms pick DM_USB.
- To keep Kconfig happy, have some select statements test for USB_HOST
as well.
- Re-order some Kconfig entries and menus so that we can cleanly pick
host or gadget roles. For the various HCD options that have platform
