Linus Torvalds 09a018176b ARM: SoC changes, part 2
This is the second part of the general SoC updates, containing
 everything that did not make it in the initial pull request,
 or that came in as a bugfix later.
 
  - Devicetree updates for SoCFPGA, ASPEED, AT91 and Rockchip, including
    a new machine using an ASPEED BMC.
 
  - More DT fixes from Krzysztof Kozlowski across platforms
 
  - A new SoC platform for the GXP baseboard management controller,
    used in current server products from HPE.
