- 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.
Fix some non-initialized variables
close the output files when done
Redo the printing for RCS strings so they don't expand in the awk script too
Do proper tests for variables existance before accessing
Verified output from all scripts is identical to original versions
in a different fashion. Individually, they have the same functionality,
but their layout is different. An example of such a chipset is
the Promise 203xx.
To be able to deal with this, transform the cmd and dma bus_space handles
into an array of handles, each seperately created with bus_space_subregion.
The code generated by using the extra indirection shouldn't change much,
since the extra indirection is negated by having the offset calculation
already done in bus_space_subregion. E.g.
bus_space_write_4(tag, handle, offset, value)
becomes
bus_space_write_4(tag, handles[offset], 0, value)

This adds a device (atabus) between IDE controllers and wd or atapibus, to
have each ATA channel show up in the device tree. Later there will be atabus
devices in /dev, so that we can do IOCTL on them.
Each atabus has its own kernel thread, to handle operations that needs polling,
e.g. reset and others.
Device probing on each bus it defered to the atabus thread creation.
This allows to do the reset and basic device probes in parallel, which reduce
boot time on systems with several pciide controllers.
removing assumptions that there are only two B channels and by
adding support for a varying number of channels.
Due to this, rename previously used isdn identified "bri" to "isdnif",
which better describes the current situation.
most polling.
2) Clean up some goofiness in pciide -- get rid of the whole "candisable" path
(it's gratuitous) and simplify the code by calling pciide_map_compat_intr(),
*_set_modes() and wdc_print_modes() from central locations.
3) Add a register writability and register ghost test to eliminate phantom
drives more quickly.
- Split if_fmv.c into MI/MD part and add ISA-PnP attachment for FMV-183.
(XXX FMV-184 is not tested. It would require extra media-select functions..)
- Fix probe functions of fmv_isa so that FMV-181A/182A will also match.
Fixes port-i386/9476.
