Off-chip peripherals should, 863when possible, adhere to the Versatile Express memory map. Non-PCI 864off-chip devices that are gem5-specific should live in the CS5 memory 865space to avoid conflicts with existing devices that we might want to 866model in the future. Such devices should normally have interrupts in 867the gem5-specific SPI range. 868 869On-chip peripherals are loosely modeled after the ARM CoreTile Express 870A15x2 A7x3 memory and interrupt map. In particular, the GIC and 871Generic Timer have the same interrupt lines and base addresses. Other 872on-chip devices are gem5 specific. 873 874Unlike the original Versatile Express RS2 extended platform, gem5 implements a 875large contigious DRAM space, without aliases or holes, starting at the 8762GiB boundary. This means that PCI memory is limited to 1GiB. 877 878Memory map: 879 0x00000000-0x03ffffff: Boot memory (CS0) 880 0x04000000-0x07ffffff: Reserved 881 0x08000000-0x0bffffff: Reserved (CS0 alias) 882 0x0c000000-0x0fffffff: Reserved (Off-chip, CS4) 883 0x10000000-0x13ffffff: gem5-specific peripherals (Off-chip, CS5) 884 0x10000000-0x1000ffff: gem5 energy controller 885 0x10010000-0x1001ffff: gem5 pseudo-ops 886 887 0x14000000-0x17ffffff: Reserved (Off-chip, PSRAM, CS1) 888 0x18000000-0x1bffffff: Reserved (Off-chip, Peripherals, CS2) 889 0x1c000000-0x1fffffff: Peripheral block 1 (Off-chip, CS3): 890 0x1c010000-0x1c01ffff: realview_io (VE system control regs.) 891 0x1c060000-0x1c06ffff: KMI0 (keyboard) 892 0x1c070000-0x1c07ffff: KMI1 (mouse) 893 0x1c090000-0x1c09ffff: UART0 894 0x1c0a0000-0x1c0affff: UART1 (reserved) 895 0x1c0b0000-0x1c0bffff: UART2 (reserved) 896 0x1c0c0000-0x1c0cffff: UART3 (reserved) 897 0x1c130000-0x1c13ffff: VirtIO (gem5/FM extension) 898 0x1c140000-0x1c14ffff: VirtIO (gem5/FM extension) 899 0x1c170000-0x1c17ffff: RTC 900 901 0x20000000-0x3fffffff: On-chip peripherals: 902 0x2b000000-0x2b00ffff: HDLCD 903 904 0x2c001000-0x2c001fff: GIC (distributor) 905 0x2c002000-0x2c003fff: GIC (CPU interface) 906 0x2c004000-0x2c005fff: vGIC (HV) 907 0x2c006000-0x2c007fff: vGIC (VCPU) 908 0x2c1c0000-0x2c1cffff: GICv2m MSI frame 0 909 910 0x2d000000-0x2d00ffff: GPU (reserved) 911 912 0x2f000000-0x2fffffff: PCI IO space 913 0x30000000-0x3fffffff: PCI config space 914 915 0x40000000-0x7fffffff: Ext.
