Machine: macppc
>Description:
After NetBSD/macppc 10.0 upgrade from 9.1, the secondary /ofwboot
fails to load 10.0 GENERIC kernel.
ofwboot from 9.1 can load the same 10.0 GENERIC kernel.

>Fix:
No idea, but there is a large set of changes in ofwboot between
9.x and 10.0:
https://github.com/NetBSD/src/commit/558e557bc9e320dfbe0fdb4678b99d607e32e270
>> - 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.)
The error message "FAILED TO CLAIM PHYS 0x%lx size 0x%lx\n" was added
in this commit. (out of VA space on /chosen/mmu ?)

It turns out this happens if "real-base" environment variable
is set as "F00000" per macppc FAQ:
http://www.netbsd.org/ports/macppc/faq.html#ofw-real-base
After changing it to the default -1 (FFFFFFFF) 10.0 ofwboot can load
GENERIC kernel.
(Note changing the value to -1 requires power cycle..)
