Hi all,
I am reporting my efforts on this thread:
* RSB/master/vanilla: riscv32 tested and builds just fine with no
changes from my side.
* RTEMS/riscv32: priv-1.10 branch - rebased with rtems/master, fixed
errors, and pushed to GitHub [1].
* RTEMS/Spike: BSP builds sample tests and tested hello/ticker on
Spike simulator.
Thanks for your efforts all.

Cheers,
Hesham
