They are next to each other and the linkcmds and symbol
table from your application should give the information.

Where did  you override the RAM size?  The linkcmds
has this:

MEMORY
{
   rom     : ORIGIN = 0x00000000, LENGTH = 256M
   ram     : ORIGIN = 0x40000000, LENGTH = 1024M
}

And the start.S zeroes out the BSS from "_edata"
to "_end".

The addresses you mentioned will be part of the
unused memory from after the bss until the end of ram
and since you didn't tell the linkcmds or RTEMS about them,
they will be put in either the Workspace or C Program Heap
and used by something.
