which calls softint_schedule(9).
We cannot use BASEPRI() to check recursive calls any longer
since softint(9) has been reorganized to use kernel thread.

XXX: This is broken: it calls methods with absolute pathnames (almost
guaranteed not to be portable across models), it accesses methods
that are in the domain of other drivers, it walks the namespace on
its own, it contains plenty of magic constants, it does not
integrate with existing KPIs, etc. Summa summarum: this should be
rewritten as a more generic toshiba_acpi(4).
because now it's patchable by binpatch(8).
Enabling serial console by DCD signal could be problematic
on some earlier TT030 (with revision A board), and it's also
annoying for users who connect an active device on the serial port
as mentioned in PR port-atari/39849.
XXX: Eventually serial console should be enabled by MD bootloader flags,
XXX: but I have no idea how to build bootloader binaries for TOS.
hardcording them in locore.s and vector.s
- also make interrupt handlers take per unit softc and put a softint cookie
into softc (though atari machines have only one zs)
- tweak some structures as per MI z8530sc driver
Tested on TT030 using sl(4) on zs.
patchable by binpatch(8) like:
---
# binpatch -s serconsole -r 0 /netbsd
serconsole(0x23bac4): 0x00000001 (1), at offset 0x23bb44 in /netbsd
new value: 0x00000000 (0)
#

May work around PR port-atari/39849
(netbsd-ATARITT kernel fails with serial port connected)
and some old TT030 with early revision boards.
Thanks to apb@ and cegger@ for initial testing.
XXX: This conflicts with hpqlb(4). Someone with the suitable hardware needs
to complete the list of hotkeys before -- and if -- this can replace
hpqlb(4). For now, the driver was left uncommented in the GENERICs.
Implemented a post-order callback to AcpiWalkNamespace. The existing
interface only has a pre-order callback. This change adds an
additional parameter for a post-order callback which will be more
useful for bus scans. ACPICA BZ 779. Lin Ming. Updated the ACPICA
Programmer Reference.
We will use the old "pre-order callback" for the time being.
- Add function to parse RDH FIS for use in implementing AT_READREG.
- Correct and clean up some structure definitions.
- Sprinkle a bit of const.
- Remove dependency on <dev/ic/wdcreg.h>, WDCTL_4BIT doesn't seem
to be specified by any recent ATA standard, and it seems to make
no difference in practice.
- Stop using WDSD_IBM, these bits have been obsolete since before SATA.
siisata:
- Implement AT_READREG.
- Reap now-unneeded <dev/ic/wdcreg.h>.
- Whitespace and slight debug code cleanup.
- Some possibly-uncessary code reordering.
ahcisata:
- Implement AT_READREG.
- Reap now-unneeded <dev/ic/wdcreg.h>.
