 1.3 17-Oct-2007  garbled branches: 1.3.20;
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.

 1.37 22-Dec-2016  cherry branches: 1.37.14;

uvm_setpagesize() is now subsumed within this funciton.
 1.36 05-Mar-2015  skrll branches: 1.36.2;
Spellos
 1.35 13-Sep-2014  matt branches: 1.35.2;

Use paddr_t for msgbufphys
 1.34 18-Aug-2013  matt <arm/locore.h> fallout (fixes some include ordering errors)
 1.33 12-Nov-2012  skrll branches: 1.33.2;
C99 types
 1.32 22-Sep-2012  matt Don't use an asm in pmap_activate to update the TTBR, use cpu_setttb instead
but add a second argument to it to indicate whether the TLB/caches need to be
flushed. Default cortex to pmap_needs_fixup = 1. But check the MMFR3 field
to see if the fixed can be skipped.
Use a cf_flag bit 0 to indicate whether the A9 L2 cache should disable (bit 0 = 1)
or enabeld (bit = 0).

With these changes, the A9 MMU can use traverse caches to do MMU tablewalks
Also, make sure all memory has the shareable bit for the A9.
 1.31 16-Aug-2012  matt branches: 1.31.2;
Move the standard definitions of the {UND,IRQ,FIQ,ABT}_STACK_SIZE to
<arm32/machdep.h>
Move the extern for cpu_reset_address to the same file.
Add cpu_reset_address_paddr.
Kill cpu_reset_v4_MMU_disable.
if cpu_reset_address is NULL, then the MMU will be disabled.
 1.30 29-Jul-2012  matt Fix more -fno-common fallout.
Move more variables to common locations.
 1.29 01-Jul-2011  dyoung branches: 1.29.2;

 1.28 30-Jun-2011  wiz dependant -> dependent
 1.27 26-Dec-2009  uebayasi Use cpu_* prefix to call cpu_* functions (setttb() -> cpu_setttb()); no
functional changes.
 1.26 26-Dec-2009  uebayasi Garbage collect an unused global, vm_offset_t pagetables_start.
 1.25 27-Nov-2009  rmind - Use uvm_lwp_setuarea() instead of directly setting address to lwp_t::l_addr.
- Replace most remaining uses of l_addr with uvm_lwp_getuarea() or lwp_getpcb().
- Amend assembly in ports where it accesses PCB via struct user.
- Rename L_ADDR to L_PCB in few places. Reduce sys/user.h inclusions.
 1.24 26-Nov-2009  matt Kill proc0paddr. Use lwp0.l_addr instead.
 1.23 21-Oct-2009  rmind Drop 3rd and 4th clauses from Ichiro FUKUHARA's license.
Reviewed and approved by ichiro@ (copyright holder).
 1.22 11-Aug-2009  matt Remove all declarations of physmem from sys/arch. Add an include of
<sys/systm.h> to the one file that did not already contain it.
This now means that physmem can be changed by updating systm.h and uvm_page.c
(excluding fixing printfs)
 1.21 14-Mar-2009  dsl Remove all the __P() from sys (excluding sys/dist)
Diff checked with grep and MK1 eyeball.
i386 and amd64 GENERIC and sys still build.
 1.20 30-Nov-2008  martin branches: 1.20.4;
As discussed on tech-kern: mutex_init is too heavyweight for early bootstrap
phases, so move the initialization of the ksyms mutex back into main via
a function called ksyms_init. Rename the existing (but quite different)
ksyms_init* variations into ksyms_addsyms_elf() and ksyms_addsyms_explicit()
and adapt machdep code accordingly.
 1.19 12-Nov-2008  ad Remove LKMs and switch to the module framework, pass 1.

Proposed on tech-kern@.
 1.18 11-Nov-2008  dyoung It is not appropriate to call pmf_system_shutdown(9) from
doshutdownhooks(9): shutdown hooks registered by shutdownhook_establish(9)
expect to be called with interrupts disabled, but shutdown hooks
registered with pmf_device_register1(9) expect to be called with
interrupts enabled. So I have made two changes:

1 Do not call pmf_system_shutdown() from doshutdownhooks(). Instead,
change every call to doshutdownhooks() to a call to doshutdownhooks()
followed by a call to pmf_system_shutdown(). No functional change
is intended by this change.

2 Make i386 re-enable interrupts briefly while it calls
pmf_system_shutdown(). I leave it to others either to fix the
other ports, or to factor out some MI shutdown code, as joerg@
suggests, and fix that. Note that a functional change *is* intended
by this change.

I hope that this patch will stop us from flip-flopping between
calling doshutdownhooks() and pmf_system_shutdown() sometimes with
and sometimes without interrupts enabled.

no-one has noticed or cared to fix it.

 1.7 04-Apr-2011  dyoung Neither pci_dma64_available(), pci_probe_device(), pci_mapreg_map(9),
pci_find_rom(), pci_intr_map(9), pci_enumerate_bus(), nor the match
predicate passed to pciide_compat_intr_establish() should ever modify
their pci_attach_args argument, so make their pci_attach_args arguments
const and deal with the fallout throughout the kernel.

For the most part, these changes add a 'const' where there was no
'const' before, however, some drivers and MD code used to modify
pci_attach_args. Now those drivers either copy their pci_attach_args
and modify the copy, or refrain from modifying pci_attach_args:

Xen: according to Manuel Bouyer, writing to pci_attach_args in
pci_intr_map() was a leftover from Xen 2. Probably a bug. I
stopped writing it. I have not tested this change.

siside(4): sis_hostbr_match() needlessly wrote to pci_attach_args.
Probably a bug. I use a temporary variable. I have not tested this
change.

slide(4): sl82c105_chip_map() overwrote the caller's pci_attach_args.
Probably a bug. Use a local pci_attach_args. I have not tested
this change.

viaide(4): via_sata_chip_map() and via_sata_chip_map_new() overwrote the
caller's pci_attach_args. Probably a bug. Make a local copy of the
caller's pci_attach_args and modify the copy. I have not tested
this change.

While I'm here, make pci_mapreg_submap() static.

With these changes in place, I have tested the compilation of these

 1.4 12-Feb-2004  scw Very occasionally, the MMU is enabled before the 'ldr' which loads
the mapped address to leap to completes. This generally manifests
itself as a random exception with RedBoot just after 'go'.

Fix it by adding a data-dependency on the 'ldr' result.
