The normal way of doing a port is to take an existing port which is
the most similar and modify it to work for your target. So if you
board is like the atlas, then use the atlas for a starting point. If
its more like a tx49 then use the tx49 as a starting point. 

In the repository you need to copy the HAL files from you choosen
starting target to a directory for your target. You then need to start
making the modifications, and add the necassary entries in the
packages/ecos.db file.

There is a documentation about doing a port. See
