Subject[PATCH v3 3/5] powerpc: wii.dts: Reduce the size of the control area
Date
This is wrong, but needed in order to avoid overlapping ranges with the
OTP area added in the next commit. A refactor of this part of the
device tree is needed: according to Wiibrew[1], this area starts at
0x0d800000 and spans 0x400 bytes (that is, 0x100 32-bit registers),
encompassing PIC and GPIO registers, amongst the ones already exposed in
this device tree, which should become children of the control@d800000
node.
