  ARM: 6533/1: Thumb-2: Make CONFIG_THUMB2_KERNEL depend on !CPU_V6
  Change bcmring Maintainer list.
  ARM: Update mach-types
  ARM: 6528/1: Use CTR for the I-cache line size on ARMv7
  ARM: 6527/1: Use CTR instead of CCSIDR for the D-cache line size on ARMv7
  ARM: pxa/palm: fix ifdef around gen_nand driver registration
  ARM: pxa: fix pxa2xx-flash section mismatch
  ARM: mmp2: remove not used clk_rtc
