[PATCH v2 2/2] m68k/q40: Replace q40ide driver with pata_falcon and falconide

From: Finn Thain
Date: Tue Jun 08 2021 - 02:04:49 EST

This allows m68k q40 systems to switch from the deprecated IDE subsystem
to libata.

Enhance the byte-swapping falconide and pata_falcon platform drivers to
accept an irq resource, for use on q40. Atari ST-DMA IRQ arrangements seem
to co-exist with q40 IRQ arrangements without too much mess.

The new IO resources were added solely for the purpose of making
request_region() reservations identical to those made by q40ide: these
regions aren't used for actual IO.

---
Note that q40ide, falconide and pata_falcon all use the same accessors
(raw_insw_swapw, raw_insw, raw_outsw_swapw, raw_outsw) and hence all
three drivers are affected by the bug relating to CONFIG_ISA and
CONFIG_ATARI_ROM_ISA which Michael has been working on recently.
This patch doesn't make that issue any better or worse.
