I honestly don't know. I never tried that. With only 14 MB of RAM,
keeping code size to the absolute minimum is quite important to me.

Aside from the lack of interrupt support for the Falcon IDE adapter in
pata_falcon: I recall some criticism regarding the size of libata a few
years back, combined with suggestion to allow libata to be built in a
more modular fashion so features not requried to support what is
essentially a dumb PIO mode IDE interface could be excluded. Not sure
what became of that.

I'd have to test both the impact of missing IDE interrupt support, and
that of code size when using either the old IDE code or libata at some
stage. Having a stable SCSI driver for the Falcon is one of the
prerequisites to that. We've just had a lot of fun with some of the m68k
SCSI drivers breaking in the 5.x kernel series, so I'd rather leave IDE
alone for now, or someone else step in and sort that particular mess out.

Cheers,

Michael
