[PATCH v5 0/3] Move qfw to DM, add Arm support

[Asherah Connor]

This series moves the QFW driver into a uclass, UCLASS_QFW, and splits
the driver into qfw_pio and qfw_mmio.  Each driver is selected on the
appropriate QEMU board.  A sandbox driver is also added, and a DM unit
test against that driver.  The qfw command is tested in QEMU, and
documentation added.

Version 5 reworks the series into three patches:
1. Do the DM conversion of existing QFW on x86
2. Add MMIO driver
3. Add the MMIO driver to qemu-arm

Changes in v5:
* Split conversion of existing x86-only QFW to DM into its own patch.
* Split MMIO driver into its own commit.
* Split adding MMIO driver to QEMU arm/64 into own commit.

Asherah Connor (3):
  x86: qemu: move QFW to its own uclass
  qemu: add MMIO driver for QFW
  qemu: arm: select QFW, MMIO on qemu-arm
