// We don't declare the IO region in here since its handled by other means.
// Dolphin allocates memory to represent four regions:
// - 24MB RAM, available on Gamecube and Wii
// - 64MB "EXRAM", RAM only available on Wii
// - 64MB FakeVMem, allocated when MMU support is turned off. This is used
// to approximate the behavior of a common library which pages memory to
// and from the DSP's dedicated RAM, which isn't directly addressable on
// GameCube.
// - 256KB Locked L1, to represent cache lines allocated out of the L1 data cache
// cache in Locked L1 mode. Dolphin does not emulate this hardware feature
// accurately; it just pretends there is extra memory at 0xE0000000.
//
// The 4GB starting at physical_base represents access from the CPU
// with address translation turned off. (This is only used by the CPU;
// other devices, like the GPU, use other rules, approximated by
// Memory::GetPointer.) This memory is laid out as follows:
// [0x00000000, 0x01800000) - 24MB RAM
// [0x08000000, 0x0C000000) - EFB "mapping" (not handled here)
// [0x0C000000, 0x0E000000) - MMIO etc. (not handled here)
// [0x10000000, 0x14000000) - 64MB RAM (Wii-only; slightly slower)
//
// The 4GB starting at logical_base represents access from the CPU
// with address translation turned on. Instead of changing the mapping
// based on the BAT registers, we approximate the common BAT configuration
// used by games:
// [0x00000000, 0x01800000) - 24MB RAM, cached access, normally only mapped
// during startup by Wii WADs
// [0x40000000, 0x50000000) - FakeVMEM
// [0x70000000, 0x80000000) - FakeVMEM
// [0x80000000, 0x81800000) - 24MB RAM, cached access
// [0x90000000, 0x94000000) - 64MB RAM, Wii-only, cached access
// [0xC0000000, 0xC1800000) - 24MB RAM, uncached access
// [0xC8000000, 0xCC000000) - EFB "mapping" (not handled here)
// [0xCC000000, 0xCE000000) - MMIO etc. (not handled here)
// [0xD0000000, 0xD4000000) - 64MB RAM, Wii-only, uncached access
// [0xE0000000, 0xE0040000) - 256KB locked L1
//
// TODO: We shouldn't hardcode this mapping; we can generate it dynamically
// based on the BAT registers.
//
// Each of these 4GB regions is followed by 4GB of empty space so overflows
// in address computation in the JIT don't access the wrong memory.
