Subject: [PATCH v1 00/10] Support for Cortex-M Prototyping System

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 (especially on uart
since I'm not sure I got it right)!

Changelog:

  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!
