My assumptions here are based in part on the names of the #defines

It was only later I re-read the README file where it states that
CFG_MONITOR_START = CFG_FLASH_BASE - makes one of them somewhat
redundant if they are equal anyway. Certainly it appears that the code
assumes they are the same!!

implementation is broken. If it happens that I have to revisit the FLASH
environment then I'll try and fix it :-))
