The OTP is a read-only memory area which contains various keys and
signatures used to decrypt, encrypt or verify various pieces of storage.
Its size depends on the console, it is 128 bytes on the Wii and
1024 bytes on the Wii U (split into eight 128 bytes banks).
It can be used directly by writing into one register and reading from
the other one, without any additional synchronisation.
This series has only been tested on the Wii U so far, using the
downstream 4.19 branch from linux-wiiu[1], but it should also work on
the Wii on mainline.

Both of these consoles use the exact same two registers, even at the
same address, but the Wii U has eight banks of 128 bytes memory while
the Wii only has one, hence the two compatible strings.
