RevisionDateAuthorComments
 1.9  06-Jul-2020  rin Include missing opt_ppcarch.h.
 1.8  18-Jan-2011  matt Add support for BookE Freescale MPC85xx (e500 core) processors.
Add fast softint support for PowerPC (though only booke uses it).
Redo FPU/VEC support and add e500 SPE support.
Rework trap/intrs to use a common trapframe format.
Support SOFTFLOAT (no hardfloat or fpu emulation) for BookE.
 1.7  25-Feb-2010  matt branches: 1.7.2; 1.7.4;
Adapt to spr.h breakup.
 1.6  05-Feb-2008  garbled branches: 1.6.10; 1.6.30; 1.6.34;
Ifdef out all the MPC601 code with PPC_OEA601. Now only arches that have the
possibility of running on an MPC601, are infected with all the extra code
and nops that it added.

Also, fix compilation that I broke with the pmap code, by adding
oeacpufeat to the locores of various ppc arches. Noted by mlelstv.
 1.5  17-Oct-2007  garbled branches: 1.5.2;
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.
 1.4  16-Feb-2006  perry branches: 1.4.24; 1.4.32; 1.4.42; 1.4.44; 1.4.46; 1.4.48;
Change "inline" back to "__inline" in .h files -- C99 is still too
new, and some apps compile things in C89 mode. C89 keywords stay.

As per core@.
 1.3  24-Dec-2005  perry branches: 1.3.2; 1.3.4; 1.3.6;
Remove leading __ from __(const|inline|signed|volatile) -- it is obsolete.
 1.2  11-Mar-2003  hannken branches: 1.2.18;
Add support for the IBM 403GCX cpu. Enabled with "options PPC_IBM403".

- different set of device control registers.
- non-standard access to the time base.
- 16 byte cache lines.

with cycle counter based microtime in kern/kern_microtime.c.

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.
