Let's work > something out. The main problem is error handling / reset code. With the current libata, basically, you can only override the whole thing pretty much at the toplevel. The problem is with things like ata_std_prereset, ata_std_softreset and ata_std_postreset and callees. We can either comletely re-implement them but that seems fairly dodgy to me, or find a way to add hooks. At the end of the day, all they need is: - write to the control register - read & write of nsect_addr & lbal_addr I wonder how much of these could be replaced by either a hook, or taskfile accessors (possibly with a special flag).
