  [MIPS] Cobalt: update reserved resources
  [MIPS] SN: PCI fixup needs to include <irq.h>.
  [MIPS] DMA: Fix a bunch of warnings due to missing inline keywords.
  [MIPS] RM: It should be #ifdef CONFIG_FOO not #if CONFIG_FOO ...
  [MIPS] Fix and cleanup the mess that a dozen prom_printf variants are.
  [MIPS] DEC: Remove redeclarations of mips_machgroup and mips_machtype.
  [MIPS] No need to write c0_compare in plat_timer_setup
  [MIPS] Convert to RTC-class ds1742 driver
