Well, it looks like I can't write that register location to 0.
It always keeps a value of 0x0001. So, it must be read-only.
It was a good idea though.
Still, I might try to find out what is there at that location out of curiosity.
Without my the 32-bit write patch, I get a lot of these messages:
sh_mobile_sdhi e804e800.sd: timeout waiting for SD bus idle
