Off-chip peripherals should, 1010when possible, adhere to the Versatile Express memory map. Non-PCI 1011off-chip devices that are gem5-specific should live in the CS5 memory 1012space to avoid conflicts with existing devices that we might want to 1013model in the future. Such devices should normally have interrupts in 1014the gem5-specific SPI range. 1015 1016On-chip peripherals are loosely modeled after the ARM CoreTile Express 1017A15x2 A7x3 memory and interrupt map. In particular, the GIC and 1018Generic Timer have the same interrupt lines and base addresses. Other 1019on-chip devices are gem5 specific. 1020 1021Unlike the original Versatile Express RS2 extended platform, gem5 implements a 1022large contigious DRAM space, without aliases or holes, starting at the 10232GiB boundary.
