Ecos port to RVDS + new board port

[Balasubramaniam, Harish]

Hi Ecos Owners,
 
 We have successfully ported Ecos source to use Arm compiler (instead of
gcc).
 We have also created a new HAL port for one of our upcoming chips
(tested in both gcc & armcc).

 We would like to know how to contribute these extensions to public
domain.

Thanks
Harish
