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.
