[PATCH 0/6] Clean up ARC code and fix IP22/28 early printk

From: Thomas Bogendoerfer

While fixing the problem of not working EARLY_PRINTK on IP22/IP28
I've removed not used ARC function and made 32bit ARC PROMs working
with 64bit kernels. By switching to memory detection via PROM calls
EARLY_PRINTK works now. And by using the regular 64bit spaces
maximum memory of 384MB on Indigo2 R4k machines is working, too.

Thomas Bogendoerfer (6):
MIPS: fw: arc: remove unused ARC code
MIPS: fw: arc: use call_o32 to call ARC prom from 64bit kernel
MIPS: Kconfig: always select ARC_MEMORY and ARC_PROMLIB for platform
MIPS: fw: arc: workaround 64bit kernel/32bit ARC problems
MIPS: SGI-IP22: set PHYS_OFFSET to memory start
MIPS: SGI-IP22/28: Use PROM for memory detection
