[PATCH v4 00/10] Support for Cortex-M Prototyping System

[Vladimir Murzin]

Hi,

This patch series provide the basic support for running ucLinux on V2M-MPS2
platform.

With these patches applied ucLinux can be run on both HW and FVP models
with Cortex-M3/M4/M7 configurations.

I'd be happy to hear any feedback/comments on this series!

Changelog:

  v3  -> v4:
      - rebased on 4.5-rc5
      - updated mps2-uart per Andy, Alan and Peter
      - dropped "zombie" EMBEDDED from defconfg per Arnd
      - moved mps2 under vexpress umbrella per Arnd
      - updated device-tree sources per Arnd
      - dropped low-level debug support, seems earlycon works well for that

  v2  -> v3:
      - rebased on 4.5-rc4
      - fixes for mps2-timer per Thomas
      - swicthed back to ttyMPS naming per Greg

  v1  -> v2:
      - rebased on 4.5-rc2
      - fixes for mps2-timer per Daniel and Rob (added Ack from Daniel)
      - fixes for mps2-uart per Greg and Andy

  RFC -> v1:
      - dropped RFC tag
      - rebased on 4.4-rc3
      - added Acks from Rob
      - updated mps2-timer per Daniel
      - fixed build failures reported by 0-DAY kernel test infrastructure

Thanks!
