Well that would mean mostly leaving out some device init code that's not
in the mainline kernel. I have not been able to boot my 1510 for a while
since the SDRAM seems to be broken on it. But at least the 16xx devices
are working, except for the MMC bug posted by Ladislav.
Below is a rough diff of the stuff that needs to be looked through for
what can be removed.
The clock changes and mailbox updates we don't want to remove, those
should go into the mainline kernel. The MMU code in the patch should
go into the dspgateway branch.
Tony
