MIPS: SGI-IP22/28: Use PROM for memory detection
EARLY_PRINTK uses ArcWrite (via prom_putchar) on IP22/28, which needs
to not mess up PROMs data structures. ARC PROM gives out a list of
memory chunks, which are used and which are free. This fixes the
problem of not working early printk.
By using XKPHYS spaces more than 256MB memory on Indigo2 R4k machines
is working now, too.

MIPS: fw: arc: workaround 64bit kernel/32bit ARC problems
Pointer arguments for 32bit ARC PROMs must reside in CKSEG0/1. While
the initial stack resides in CKSEG0 the first kernel thread stack
is already placed at a XKPHYS address, which ARC32 can't handle.
The workaround here is to use static variables, which are placed
into BSS and linked to a CKSEG0 address.

MIPS: fw: arc: use call_o32 to call ARC prom from 64bit kernel
When using a 64bit kernel with generic spaces setup stack is
also placed in XKPYHS, which the 32bit PROM can't handle.
By using call_o32 for ARC_CALLs a stack placed in KSEG0 is used
when calling PROM.
