So, as far as I have understood, here are the following points which need to 
be considered for RTEMS-based development:

1. Check if the CPU is supported: Cortex-R CPUs are supported as per the 
wiki page http://www.rtems.org/wiki/index.php/ARM-EABI

2. Write a BSP for the requisite Board as it is not available for mine - 
This part I will figure out in due time.

But kindly confirm statement 1. 
I have read your previous comment about the template LPC32XX BSP.
I will be using the Texas Instrument Microcontroller TMS570LS3137 for the 
development. http://www.ti.com/product/tms570ls3137

I just need a confirmation whether my understanding to this stage is 
correct. Only then will it make sense to commit to developing the requisite 
BSP.
