Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/sparc-next-2.6
* 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 ...
