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.

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!
