Updated (thanks to a quick eye by ebs) patch to add CPM2 SDMA and BitBang I2C support to the MPC85xx This patch gets rid of some really stupid cut & paste errors during initialization. -- Jason McMullan [off-list ref] TimeSys Corporation

[snip] Jason, another thought. Do we really need all this mess with separate algo and bus drivers? Could you make just a bus driver like we have for 4xx, Keywest and 85xx/52xx/MPC107? It's much cleaner and less confusing IMHO. -- Eugene

I made it separate algo/bus in case you had a PCI-card 85xx design
where:
a) You booted the card with firmware
b) The firmware made the card a PCI device with the CPM exposed
before you booted the kernel.
c) The PCI host had to program an EEPROM on the CPM I2C bus
for configuration to tell it where to get the kernel.
Admittedly, a little far out, but then you could make a
CPM-exposed-by-PCI I2C bus driver.
