| The VExpress gem5 memory map is loosely based on a modified |
| Versatile Express RS1 memory map. |
| |
| 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. |
| |
| On-chip peripherals are loosely modeled after the ARM CoreTile Express |
| A15x2 memory and interrupt map. In particular, the GIC and |
| 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. |
