- When starting the boot program, cache a bunch of OFW frequently used
ihandles / phandles, rather than fetching them all the time.
- Change the signature of OF_call_method() to take an array of cells for
the inputs and outputs, rather than using variadic arguments. This
makes it much easier to use OF_call_method() when the format of the
arguments passed to a given method are determined at run-time
(due to e.g. #address-cells).
- Properly inform OpenFirmware where the kernel is loaded by using
"claim" on /chosen/memory and, if running in virtual-mode, using
"claim" on /chosen/mmu to reserve the VA, and "map" on /chosen/mmu
to enter the translation. (The kernel is still always mapped VA==PA.)

When boot up with auto-boot? == true, some systems do not provide stdout
if the normal output is screen.

Open screen explicitly as stdout in this case, both for ofwboot and kernel,
which fixes problems with auto-boot? == true for Mac mini G4:

- messages from ofwboot do not appear
- kernel freeze during early boot stage

PR 51495/port-macppc

Allow ppc601 to boot off hard disk

- add some G5-specific setup
- OF_claim() more heap space on G5
With this, and -DHEAP_VARIABLE my G5s boot from harddisk

Provide commented out OF_enter() that comes in handy when debugging.

Provide an option to use libsa allocator. Not yet enabled. Same
binary code is generated.

To enable uncomment -DHEAP_VARIABLE and comment out alloc.c in the
makefile.

Don't set garbages into BAT registers, which was broken in rev 1.25.

Undo my half hearted atttempt at porting ofwboot to the G5.
Thanks to Cherry for pointing this out, and my apologies.

1st cut of Powermac G5 support (uses bridge mode).

More constification.

Tell gcc that startup and stack are used.
In startup remove declarations of unused symbols.
This file now compiles with WARNS=4.

Make -Wcast-qual happy.

This has been lying around in my tree for too long now.

Oops, didn't mean to commit this.

Use PAGE_SIZE rather than NBPG.

Convert to register prefixes. Use ANSI string concatenation for

Remove vestiges of the syncicache() call originally in powerpc/ofwboot
before rev 1.4. This change makes OF 2.4 machines actually boot, and
it works fine on my OF 2.01 machine. No reports of failures on other
archs.

I expect this change is fine as the original code flushed the just-loaded
ofwboot out of the cache, conditionalized on FIRMWORKSBUGS. In rev.
1.4, the code got in-lined, and changed to actually flush low memory
out of the cache. Since machines kept booting, I expect the firmware
was really flushing the binary out of the cache, so we're fine.
