[RFC PATCH 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!

Remain questions:

 - Application notes 399/400 have PSRAM located at address different to what
   we have for AN385/AN386, so I'm wondering what is the best practice to handle
   CONFIG_DRAM_BASE? Different defconfig or there is better place?

 - I'm not sure about naming of dts files: Application Notes (mps2-an*) vs Cortex-M (mps2-cm*);
   any preference?

P.S.

This series is against 4.4-rc1.

Thanks!
