* git://git.kernel.org/pub/scm/linux/kernel/git/davem/sparc-next-2.6: (25 commits)
atyfb: Fix bootup hangs on sparc64.
sparc: update copyright in piggyback.c
sparc: unify strip command in boot/Makefile
sparc: rename piggyback_32 to piggyback
sparc: fix tftpboot.img for sparc64 on little-endian host
sparc: add $BITS to piggyback arguments
sparc: remove obsolete ELF support in piggyback_32.c
sparc: additional comments to piggyback_32.c
sparc: use _start for the start entry (like 64 bit does)
sparc: use trapbase in setup_arch
sparc: refactor piggy_32.c
Added support for ampopts in APBUART driver. Used in AMP systems.
APBUART: added raw AMBA vendor/device number to match against.
SPARC/LEON: avoid AMBAPP name duplicates in openprom fs when REG is missing
SPARC/LEON: added support for selecting Timer Core and Timer within core
LEON: added raw AMBA vendor/device number to find TIMER, IRQCTRL
SPARC/LEON: added support for IRQAMP IRQ Controller
SPARC/LEON: find IRQCTRL and Timer via OF-Tree, instead of hardcoded.
sparc: fix sparse warnings in arch/sparc/prom for 32 bit build
sparc: remove unused prom tree functions
