Off-chip peripherals should, 778when possible, adhere to the Versatile Express memory map. Non-PCI 779off-chip devices that are gem5-specific should live in the CS5 memory 780space to avoid conflicts with existing devices that we might want to 781model in the future. Such devices should normally have interrupts in 782the gem5-specific SPI range. 783 784On-chip peripherals are loosely modeled after the ARM CoreTile Express 785A15x2 A7x3 memory and interrupt map. In particular, the GIC and 786Generic Timer have the same interrupt lines and base addresses. Other 787on-chip devices are gem5 specific. 788 789Unlike the original Versatile Express RS2 extended platform, gem5 implements a 790large contigious DRAM space, without aliases or holes, starting at the 7912GiB boundary. This means that PCI memory is limited to 1GiB. 792 793Memory map: 794 0x00000000-0x03ffffff: Boot memory (CS0) 795 0x04000000-0x07ffffff: Reserved 796 0x08000000-0x0bffffff: Reserved (CS0 alias) 797 0x0c000000-0x0fffffff: Reserved (Off-chip, CS4) 798 0x10000000-0x13ffffff: gem5-specific peripherals (Off-chip, CS5) 799 0x10000000-0x1000ffff: gem5 energy controller 800 0x10010000-0x1001ffff: gem5 pseudo-ops 801 802 0x14000000-0x17ffffff: Reserved (Off-chip, PSRAM, CS1) 803 0x18000000-0x1bffffff: Reserved (Off-chip, Peripherals, CS2) 804 0x1c000000-0x1fffffff: Peripheral block 1 (Off-chip, CS3): 805 0x1c010000-0x1c01ffff: realview_io (VE system control regs.) 806 0x1c060000-0x1c06ffff: KMI0 (keyboard) 807 0x1c070000-0x1c07ffff: KMI1 (mouse) 808 0x1c090000-0x1c09ffff: UART0 809 0x1c0a0000-0x1c0affff: UART1 (reserved) 810 0x1c0b0000-0x1c0bffff: UART2 (reserved) 811 0x1c0c0000-0x1c0cffff: UART3 (reserved) 812 0x1c170000-0x1c17ffff: RTC 813 814 0x20000000-0x3fffffff: On-chip peripherals: 815 0x2b000000-0x2b00ffff: HDLCD 816 817 0x2c001000-0x2c001fff: GIC (distributor) 818 0x2c002000-0x2c0020ff: GIC (CPU interface) 819 0x2c004000-0x2c005fff: vGIC (HV) 820 0x2c006000-0x2c007fff: vGIC (VCPU) 821 0x2c1c0000-0x2c1cffff: GICv2m MSI frame 0 822 823 0x2d000000-0x2d00ffff: GPU (reserved) 824 825 0x2f000000-0x2fffffff: PCI IO space 826 0x30000000-0x3fffffff: PCI config space 827 828 0x40000000-0x7fffffff: Ext.
