  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.
