Off-chip peripherals should, 763when possible, adhere to the Versatile Express memory map. Non-PCI 764off-chip devices that are gem5-specific should live in the CS5 memory 765space to avoid conflicts with existing devices that we might want to 766model in the future. Such devices should normally have interrupts in 767the gem5-specific SPI range. 768 769On-chip peripherals are loosely modeled after the ARM CoreTile Express 770A15x2 A7x3 memory and interrupt map. In particular, the GIC and 771Generic Timer have the same interrupt lines and base addresses. Other 772on-chip devices are gem5 specific. 773 774Unlike the original Versatile Express RS2 extended platform, gem5 implements a 775large contigious DRAM space, without aliases or holes, starting at the 7762GiB boundary. This means that PCI memory is limited to 1GiB. 777 778Memory map: 779 0x00000000-0x03ffffff: Boot memory (CS0) 780 0x04000000-0x07ffffff: Reserved 781 0x08000000-0x0bffffff: Reserved (CS0 alias) 782 0x0c000000-0x0fffffff: Reserved (Off-chip, CS4) 783 0x10000000-0x13ffffff: gem5-specific peripherals (Off-chip, CS5) 784 0x10000000-0x1000ffff: gem5 energy controller 785 0x10010000-0x1001ffff: gem5 pseudo-ops 786 787 0x14000000-0x17ffffff: Reserved (Off-chip, PSRAM, CS1) 788 0x18000000-0x1bffffff: Reserved (Off-chip, Peripherals, CS2) 789 0x1c000000-0x1fffffff: Peripheral block 1 (Off-chip, CS3): 790 0x1c010000-0x1c01ffff: realview_io (VE system control regs.) 791 0x1c060000-0x1c06ffff: KMI0 (keyboard) 792 0x1c070000-0x1c07ffff: KMI1 (mouse) 793 0x1c090000-0x1c09ffff: UART0 794 0x1c0a0000-0x1c0affff: UART1 (reserved) 795 0x1c0b0000-0x1c0bffff: UART2 (reserved) 796 0x1c0c0000-0x1c0cffff: UART3 (reserved) 797 0x1c170000-0x1c17ffff: RTC 798 799 0x20000000-0x3fffffff: On-chip peripherals: 800 0x2b000000-0x2b00ffff: HDLCD 801 802 0x2c001000-0x2c001fff: GIC (distributor) 803 0x2c002000-0x2c0020ff: GIC (CPU interface) 804 0x2c004000-0x2c005fff: vGIC (HV) 805 0x2c006000-0x2c007fff: vGIC (VCPU) 806 0x2c1c0000-0x2c1cffff: GICv2m MSI frame 0 807 808 0x2d000000-0x2d00ffff: GPU (reserved) 809 810 0x2f000000-0x2fffffff: PCI IO space 811 0x30000000-0x3fffffff: PCI config space 812 813 0x40000000-0x7fffffff: Ext.
