  xtensa: Add config files for Diamond 232L - Rev B processor variant
  xtensa: Fix io regions
  xtensa: Add support for the Sonic Ethernet device for the XT2000 board.
  xtensa: replace remaining __FUNCTION__ occurrences
  xtensa: use newer __SPIN_LOCK_UNLOCKED macro
  XTENSA: warn about including <asm/rwsem.h> directly.
