vexpress64: Add ARMv8R-64 board variant
The ARMv8-R64 architecture introduces optional VMSA (paging based MMU)
support in the EL1/0 translation regime, which makes that part mostly
compatible to ARMv8-A.
Add a new board variant to describe the "BASE-R64" FVP model, which
inherits a lot from the existing v8-A FVP support. One major difference
is that the memory map in "inverted": DRAM starts at 0x0, MMIO is at
2GB [1].
* Create new TARGET_VEXPRESS64_BASER_FVP target, sharing most of the
exising configuration.
* Implement inverted memory map in vexpress_aemv8.h
* Create vexpress_aemv8r defconfig
* Provide an MMU memory map for the BASER_FVP
* Update vexpress64 documentation
At the moment the boot-wrapper is the only supported secure firmware. As
there is no official DT for the board yet, we rely on it being supplied
by the boot-wrapper into U-Boot, so use OF_HAS_PRIOR_STAGE, and go with
a dummy DT for now.
