wdc_regs structure, and array of which (indexed per channel) is pointed
to by struct wdc_softc.
- Move the resulting wdc_channel structure to atavar.h and rename it to
ata_channel. Rename the corresponding flags.
- Add a "ch_ndrive" member to struct ata_channel, which indicates the
maximum number of drives that can be present on the channel. For now,
this is always 2. Add an ATA_MAXDRIVES constant that places an upper
limit on this value, also currently 2.
to all GENERIC-like kernel config files where SYSV* options were already
present (commented out if the SYSV* options are commented out).
Fix lib/25897 and lib/25898.
(minimum desired free memory), default them to 5M and 10M respectively.
On a machine with more than (BOOT_LEAVE_MEMORY + BOOT_MIN_AVAIL_MEMORY) free
BOOT_LEAVE_MEMORY will be left unused.
Allows a kernel to be booted from SparkFS on a machine with more than 15M
of free memory (SparkFS needs to be able to allocate memory for the
uncompressed kernel)
registers are registers that overlap with others on many controllers, but
which may actually be distinct on some controllers. Right now, the two
shadows are:
- wd_status (usually overlaps wd_command)
- wd_features (usually overlaps wd_error)
Add a new helper function, wdc_init_shadow_regs(), used to initialize
the shadow register handles on controllers where they do actually overlap.

bubblesort in acorn32 bootloader. Reduces time to sort memory on A710 equipped
RiscPC from over twenty seconds to effectively instantaneous.
Update boot version to 3.30
the need to explicitly set the WIMP slot size before running the bootloader.
Conditional on BOOT_MAXIMISE_MEMORY, so as not to interfere with potential
future uses of libriscos.
Also remove references to increasing WIMP slot size, as this is now
meaningless.
* lpt device is defined in MI place (dev/ppbus/files.ppbus), dev/ic/lpt.c
is included there too; dev/ic/lpt.c is not included if ppbus is
configured or if there is alternative platform lpt (like for pc532)
* g/c MD lpt definitions and custom puc/upc attachments,
glue moved to conf/files and dev/pci/files.pci respectively; remove
device lpt definition from dev/isa/files.isa
* add ppbus parport attribute, atppc device attachments, adjust plip and lpt
glue
Remove the vestigal sysbeep device and replace it with the same kind of
mechanism that pckbd(4) uses to find the bell, which is just as ugly, but
more standard. Adapt beep(4) to the new world (though I'm not sure it
deserves to live).
Get rid of the static bus tag, instead move it into the softc.
Update to ThorpeJ's recent variable renaming for ATA things.
De-__P and KNF prototypes, also make attach and probe static.
Add RCSID.
Add a copyright for myself.
acccesses with addresses shifted by the amount specified in the cookie.
Also make the inclusion of the wscons file the resposibility of whoever
includes files.iomd. (found while attempting to checking riscstation
support into evbarm)

also available with RISC-OS as a RiscStation:

This is basic bootstrap with support for ide and networking, currently only
tested with booting from ABLE, and not RISC-OS.
I would have placed it into evbarm, but iomd doesn't appear to use the same
interrupt files as evbarm. I'll check it into here for now, until iomd
uses the common interrupt code.
- wdc_xfer to ata_xfer
- channel_queue to ata_queue
and move them to <dev/ata/atavar.h> so they can be used by non-wdc ATA
controllers. Clean up the member names of these structures while at it.
