andvar | Fix DMAC_ARRAYCHAIN enabled build:
pass dmac->sc_dev instead of undefined self in dmac_start_xfer_offset().
remove unused chan/ch variables in dmac_program_arraychain().
initialize c to zero in dmac_start_xfer_offset() and add check that is bigger
than 0 before calling dma_cachectl() to fix potentially uninitialized error
(seems to be false positive though).

To abort DMA in dmac_abort_xfer(), set DMAC_CCR_SAB (software abort)
rather than DMAC_CCR_HLT (halt operation).
DMAC_CCR_HLT doesn't abort DMA xfers but only suspends DMA ops
(i.e. clearing HLT bit will resume DMA xfers), so previously
DMAC error always occurs on the next DMA xfer ops after
dmac_abort_xfer() is called.
Also suppress DMAC error messages in dmac_error() if it's caused
by software abort command because it can happen during normal
audio play/record DMA ops in vs(4) driver.

Merge the ppcoea-renovation branch to HEAD.
This branch was a major cleanup and rototill of many of the various OEA
cpu based PPC ports that focused on sharing as much code as possible
between the various ports to eliminate near-identical copies of files in
every tree. Additionally there is a new PIC system that unifies the
interface to interrupt code for all different OEA ppc arches. The work
for this branch was done by a variety of people, too long to list here.
TODO:
bebox still needs work to complete the transition to -renovation.
ofppc still needs a bunch of work, which I will be looking at.
ev64260 still needs to be renovated
amigappc was not attempted.
NOTES:
pmppc was removed as an arch, and moved to a evbppc target.

Explicitly specify a proper FDC data register address for HD63450 DMAC
to avoid confusion.
Previous one (fdc->sc_addr + fddata) wasn't a right address for
the FDC's data register but one for the command register by accident,
but FDC ignores A0 address input (connected to A1 of x68k address bus)
during DMA xfer (i.e. when DACK is asserted) so it happened to work
as expected on the real X680x0 hardware, but caused trouble on emulators.
The inconsistency was found by Y.Sugahara during debugging XM6i emulator
(and it will be fixed in the next release).
FDC behavior during DMA is confirmed by uPD72068 hardware application note.
XXX: There is no proper MI API to specify DMA address for DMA controller
(like MC68450) to access devices mapped to memory space by bus_space(9).
- use <sys/bus.h> rather than <machine/bus.h>
- no need to include uvm_extern.h
- include "ioconf.h" for struct cfdriver foo_cd
KNF and cosmetics. No binary change.
- check bus_space_map(9) return value
- use BUS_SPACE_MAP_SHIFTED_ODD for clarify
- define and use proper macro instead of magic
To abort DMA in dmac_abort_xfer(), set DMAC_CCR_SAB (software abort)
rather than DMAC_CCR_HLT (halt operation).
DMAC_CCR_HLT doesn't abort DMA xfers but only suspends DMA ops
(i.e. clearing HLT bit will resume DMA xfers), so previously
DMAC error always occurs on the next DMA xfer ops after
dmac_abort_xfer() is called.
Also suppress DMAC error messages in dmac_error() if it's caused
by software abort command because it can happen during normal
audio play/record DMA ops in vs(4) driver.
Before probing floppy drives, call NE7CMD_SENSEI and fdcresult()
to drain possible pending FDC interrupts. Taken from sys/dev/isa/fd.c.
Hopefully might fix occasional fd drive probe failure (but not confirmed).
Terminate DMAC and call bus_dmamap_unload(9) properly in all FDC xfer
error paths, as sys/dev/isa/fd.c does. Fixes unexpected DMAC errors
(and possible VM panic due to un-unloaded dmamap) on the first floppy
access after read/write errors.
Add floppy format support. Mostly taken from sys/dev/isa/fd.c.
Tested both fdNa (1232KB, 1024bytes/sector, 8sectors/track) and
fdNc (1200KB, 512bytes/sector, 15sectors/track) format on X68030
using fdformat(1).
Finally we can prepare NetBSD/x68k install floppies without Human68k
(except actual initial bootstrap).
