[MiNT] Block device driver interface (was: Kentry)

[Standa Opichal <opichals@seznam.cz>]

Hi!

I would also like to contribute to this as I see a good opportunity to 
get native ARAnyM disk access instead of going through the IDE 
emulation. Is this something we can do with that? If I understand it 
correctly yes.. or?

My idea is to create /dev/hdX devices that would use a common XHDI block 
device driver implementation driver (parametrized) that would be an 
implementation of the interface to be designed. I suppose we want to 
replace the buffer cache calls away from the filesystems implementation 
and instead use the new interface there. Or would that work the other 
way around? I mean the buffer cache would stay in place and it would use 
the block device driver interface underneath (this makes more sense to 
me at the moment)..
