ArmPlatformPkg/ArmVirtualizationPkg: Add ArmVirtualizationQemu platform
This adds support for executing UEFI in a QEMU/mach-virt emulated environment.
The following assumptions are made about the target:
- DRAM base at 0x4000_0000, containing the device tree blob
- DRAM size at least 1 MB
- device tree uses 64-bit physical base addresses and sizes
- ARM architected timer
- Cortex-A15 CPU (if built for 32-bit)
The following information is retrieved from the device tree:
- PL011 UART base address
- GIC base addresses
- virtual timer interrupt
- PL031 RTC base address
- DRAM size, must be at least 128 MB
- virtio MMIO transports
- PSCI 0.2 availability (for reset and poweroff)
The device tree image is relocated and installed as a configuration table
so an EFI stub enabled kernel can be booted directly without the need for
a bootloader.
