Model for an ATA driver

[Olivier Gautherot]

Hi folks!

I started investigating how to generate a native ATA driver for the Efika
as an alternative to the OFW-based Nexus emulation - the idea is to provide
write access in the future to edit partitions.

Does anyone have recommendations to approach this? I've found code in
/usr/src/sys/dev/ata/ata-chipset.c (seems to be a pot-pourri of all 
architectures) but don't see the registers allocation...

Any hint welcome
Cheers
