mid or long term goal is to run RTEMS on my mini2440 board[1].

Hi,

AFAIK there is no official BSP support for mini2440. There was a discussion
roughly 4 years back with Bacon Xu regarding a patch that adds the support
to rtems 4.10.2. However, I couldn't find it in the mailing list archive,
perhaps the list was cleaned.
The patch was never merged into the upstream and I'm not sure if it was
published on the web at all. I found it in my files and have attached it to
the email.
There is another patch for mini2440 support on rtems 4.10.*1*, which you
can find at: http://blog.csdn.net/rickleaf/article/details/7067581. Please
note however that it doesn't work right out-of-the-box and needs additional
modifications.

Best Regards,
Saeed
