Bash Script to find discrepancies in BSP file organization

Hello Gedare,

I reviewed the current documentation for bsp development as you suggested. I didn't find any major discrepancies present already, but will look again closely. As far I think, the part about the PIC support which is available to every BSP is currently not present in the documentation, so I'll submit the addition to docs regarding this if you also agree to it. 

My current script gives results on a per bsp basis. However, as you requested to classify the problems, I've done that by tweaking it a little. I've added the functionality to search for RTEMS internal functions being used in the bsp. From what I understood, these internal functions I've looked for in BSPs are taken from libcpu & cpukit. 

My aim in developing this bash script was to identify flaws in BSPs , and also to provide a simple tool for future BSP developers so that they can check the file organization for their BSP. So, is it fine if I submit a patch to add this script to the RTEMS tree ??

Following, you'll find discrepancies found in current RTEMS tree regarding some serious flaws. The attached file all_warnings.txt classifies the flaws found in all bsps, either it being serious or not. The attached file 'per_bsp_observation.txt' contains result of the script showing serious flaws in all the bsps.
