Andrew Walbran 13cbc69abc aarch64: Don't include pVM firmware region in memory size calculation. 
The pVM firmware memory region is allocated before
AARCH64_PHYS_MEM_START, but several parts of the code were assuming that
all memory was contiguous and after that.

BUG=b:244553205
TEST=Patched into AOSP and ran some VMs.

crosvm - The Chrome OS Virtual Machine Monitor

crosvm is a virtual machine monitor (VMM) based on Linux’s KVM hypervisor, with a focus on simplicity, security, and speed. crosvm is intended to run Linux guests, originally as a security boundary for running native applications on the Chrome OS platform. Compared to QEMU, crosvm doesn’t emulate architectures or real hardware, instead concentrating on paravirtualized devices, such as the virtio standard.

crosvm is currently used to run Linux/Android guests on Chrome OS devices.
