 1.14  18-Oct-2016  jdolecek add isa_intr_establish_xname() to MD isa headers so that it can be used
by MI drivers

isa_detach_hook() needs two arguments, the first an isa_chipset_tag_t.

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.

merge ktrace-lwp.
 1.8  07-Aug-2003  agc branches: 1.8.16;
Move UCB-licensed code from 4-clause to 3-clause licence.

Patches provided by Joel Baker in PR 22364, verified by myself.
 1.7  09-May-2003  fvdl branches: 1.7.2;
A few ISA sound drivers like to share dma channels, and hence deferred
isa_dmamap_create() calls to their open/close entrypoints. This worked
with some luck, but broke on i386 when _bus_dmamap_create started
to allocate bounce buffers upfront, since memory below 16M may well
not be available when the sound devices is opened for the Nth time.

To fix this, create a new simple interface, isa_drq_alloc/isa_drq_free,
wrappers around already existing bitmask macros. These are expected
to be used before an isa_dmamap_create call, and after an
isa_dmamap_destroy call, respectively. For the sb and ad1848 drivers,
they're deferred until open/close.

All isa_dmamap_create calls can now use BUS_DMA_ALLOCNOW and be done
at attach time.
 1.6  26-Aug-2001  matt branches: 1.6.6;
Make all powerpc ports use a common Makefile.powerpc (except walnut)
Enforce -Wmissing-prototypes -Wstrict-prototypes for all ppc ports.
Split out macppc cpu support and make common to mpc6xx ports. Make
other mpc6xx ports use it. Add evcnts for mpc6xx traps.
 1.5  15-Jun-2001  nonaka branches: 1.5.2;
Use new common bus.h framework.
 1.4  15-Nov-2000  thorpej branches: 1.4.2; 1.4.4;
Move the ISA DMA cookie into isadma_machdep.c.
 1.3  04-Jun-2000  cgd Implement the more flexiable `evcnt' interface as discussed (briefly) on
tech-kern and now documented in evcnt(9).
 1.2  01-Jun-2000  cgd kill __P in these files. (I had to look at them anyway with an eye for
adding some protos... and adding them with __P seems wrong, but mixing
__P and not __P in the same file seems wrong too, so...)
 1.1  29-Feb-2000  nonaka branches: 1.1.2;
Initial import prep port.
 1.1.2.1  22-Jun-2000  minoura Sync w/ netbsd-1-5-base.
 1.4.4.1  21-Jun-2001  nathanw Catch up to -current.
 1.4.2.3  22-Nov-2000  bouyer Sync with HEAD.
 1.4.2.2  20-Nov-2000  bouyer Update thorpej_scsipi to -current as of a month ago
A i386 GENERIC kernel compiles without the siop, ahc and bha drivers
(will be updated later). i386 IDE/ATAPI and ncr work, as well as
sparc/esp_sbus. alpha should work as well (untested yet).
siop, ahc and bha will be updated once I've updated the branch to current
-current, as well as machine-dependant code.

Follow the merge of pmap.c on i386 and amd64 and move
pmap_init_tmp_pgtbl into arch/x86/x86/pmap.c. Modify the ACPI wakeup
code to restore CR4 before jumping back into kernel space as the large
page option might cover that.
 1.9.38.3  07-May-2007  garbled Convert prep over to new isa_machdep changes.
 1.9.38.2  03-May-2007  garbled Get rid of all the useless stuff in isa_machdep.c, and the things that
call it. TODO, fix isa_intr_alloc to work with new interrupt foo.
