The VExpress gem5 memory map is loosely based on a modified

The gem5 platform has been designed to implement a subset of the
original Versatile Express RS1 memory map. Off-chip peripherals should,
when possible, adhere to the Versatile Express memory map. Non-PCI
off-chip devices that are gem5-specific should live in the CS5 memory
space to avoid conflicts with existing devices that we might want to
model in the future. Such devices should normally have interrupts in
the gem5-specific SPI range.

Generic Timer have the same interrupt lines and base addresses. Other
on-chip devices are gem5 specific.
Unlike the original Versatile Express RS2 extended platform, gem5 implements a
large contigious DRAM space, without aliases or holes, starting at the
2GiB boundary. This means that PCI memory is limited to 1GiB.
