| |
Hi! Quick question: is it possible to write an IDE driver for a controller that is not mappable using outp and those memory-mapped thingys ?
I see all the nice overrideables in struct hwif_s but the main code still uses OUT_BYTE which is hardcoded to an outb_p.. non-overrideable. Same thing with ide_input/output_bytes, they do direct in/out accesses also without consulting any hwif specific routine.
So what do I do if my controller does not have a simple memory-mapping for each IDE-register into the memory ? Do I have to clutter ide.h and ide.c with #ifdef's or is there any cleaner abstraction on the way (something like adding a hwif field to perform the OUT/IN-byte stuff, and ide_xxput_bytes) ?
(I have a solution working by replacing OUT_BYTE and ide_xxput_bytes, but wanted to make it without having to patch the "official" ide.c/ide.h)
Regards, Bjorn
