Linus Torvalds 24e44913aa ARM: SoC platform updates
SoC platform changes. Main theme this merge window:
 
  - The Netx platform (Netx 100/500) platform is removed by Linus Walleij--
    the SoC doesn't have active maintainers with hardware, and in
    discussions with the vendor the agreement was that it's OK to remove.
 
  - Russell King has a series of patches that cleans up and refactors
    SA1101 and RiscPC support.
