Yes, but you talked about "We cannot import the YML data in external 
code without coping it...". I assumed this referred to the RTEMS Tools.

Lets assume you have a BSP which has its RAM origin at A or B depending 
on the BSP configuration options. If you have a BSP installed configured 
to use A, then the bootloader image probably needs to be created using 
A. If it is configured to use B, it needs to use B.
