 1.10  18-Oct-2016  jdolecek add isa_intr_establish_xname() to MD isa headers so that it can be used
by MI drivers
 1.9  19-Aug-2009  dyoung branches: 1.9.22; 1.9.40; 1.9.44;
isa_detach_hook() needs two arguments, the first an isa_chipset_tag_t.
 1.8  19-Aug-2009  dyoung Define isa_detach_hook().
 1.7  28-Apr-2008  martin Remove clause 3 and 4 from TNF licenses
 1.6  17-Oct-2007  garbled branches: 1.6.16; 1.6.18; 1.6.20;
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.
 1.5  11-Dec-2005  christos branches: 1.5.30; 1.5.38; 1.5.48; 1.5.50; 1.5.52; 1.5.54;
merge ktrace-lwp.
 1.4  07-Aug-2003  agc branches: 1.4.16;
Move UCB-licensed code from 4-clause to 3-clause licence.

Patches provided by Joel Baker in PR 22364, verified by myself.
 1.3  09-May-2003  fvdl branches: 1.3.2;
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.
 1.2  10-Jun-2001  briggs branches: 1.2.8;

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.

- adapt powerpc/pic cascadable PIC dispatching scheme.
- import bus.h, intr.h and isa_machdep.h from prep.
- make openpicreg.h EPIC register locator somehow flexible.
