IO registers starting at physical address 0x10200000 are not accessible from the ARM9 (which includes all LCD/GPU registers). It seems IO registers below physical address 0x10100000 are not accessible from the ARM11 bus.
IO rgstrs starting at physical address 0x10200000 are not accessible from the ARM9 (which includes all LCD/GPU rgstrs). It seems IO rgstrs below physical address 0x10100000 are not accessible from the ARM11 bus.


ARM11 kernel virtual address mappings for these registers varies for different builds. For ARM11 user mode applications you have:
ARM11 kernel virtual address mappings for these rgstrs varies for different builds. For ARM11 user mode applications you have:
