Off-chip peripherals should, 798when possible, adhere to the Versatile Express memory map. Non-PCI 799off-chip devices that are gem5-specific should live in the CS5 memory 800space to avoid conflicts with existing devices that we might want to 801model in the future. Such devices should normally have interrupts in 802the gem5-specific SPI range. 803 804On-chip peripherals are loosely modeled after the ARM CoreTile Express 805A15x2 A7x3 memory and interrupt map. In particular, the GIC and 806Generic Timer have the same interrupt lines and base addresses. Other 807on-chip devices are gem5 specific. 808 809Unlike the original Versatile Express RS2 extended platform, gem5 implements a 810large contigious DRAM space, without aliases or holes, starting at the 8112GiB boundary. This means that PCI memory is limited to 1GiB. 812 813Memory map: 814 0x00000000-0x03ffffff: Boot memory (CS0) 815 0x04000000-0x07ffffff: Reserved 816 0x08000000-0x0bffffff: Reserved (CS0 alias) 817 0x0c000000-0x0fffffff: Reserved (Off-chip, CS4) 818 0x10000000-0x13ffffff: gem5-specific peripherals (Off-chip, CS5) 819 0x10000000-0x1000ffff: gem5 energy controller 820 0x10010000-0x1001ffff: gem5 pseudo-ops 821 822 0x14000000-0x17ffffff: Reserved (Off-chip, PSRAM, CS1) 823 0x18000000-0x1bffffff: Reserved (Off-chip, Peripherals, CS2) 824 0x1c000000-0x1fffffff: Peripheral block 1 (Off-chip, CS3): 825 0x1c010000-0x1c01ffff: realview_io (VE system control regs.) 826 0x1c060000-0x1c06ffff: KMI0 (keyboard) 827 0x1c070000-0x1c07ffff: KMI1 (mouse) 828 0x1c090000-0x1c09ffff: UART0 829 0x1c0a0000-0x1c0affff: UART1 (reserved) 830 0x1c0b0000-0x1c0bffff: UART2 (reserved) 831 0x1c0c0000-0x1c0cffff: UART3 (reserved) 832 0x1c170000-0x1c17ffff: RTC 833 834 0x20000000-0x3fffffff: On-chip peripherals: 835 0x2b000000-0x2b00ffff: HDLCD 836 837 0x2c001000-0x2c001fff: GIC (distributor) 838 0x2c002000-0x2c0020ff: GIC (CPU interface) 839 0x2c004000-0x2c005fff: vGIC (HV) 840 0x2c006000-0x2c007fff: vGIC (VCPU) 841 0x2c1c0000-0x2c1cffff: GICv2m MSI frame 0 842 843 0x2d000000-0x2d00ffff: GPU (reserved) 844 845 0x2f000000-0x2fffffff: PCI IO space 846 0x30000000-0x3fffffff: PCI config space 847 848 0x40000000-0x7fffffff: Ext.
