The value of the register during normal operation seems to depend on Hollywood revision.
The value of the register during normal operation seems to depend on Hollywood revision.
* In boot1c, if the Hollywood version bits (in HW_VERSION) are 0, this is set to 0x47 (otherwise, set to 0x7).
* In boot1c, set to 0x47 if HWVER (in HW_VERSION) is 0 - otherwise, set to 0x7.
It seems like bits 31-7 cannot be read or written to? {{check}}
