I am confused about ARM and the use of TEXT_BASE:
That's understandable.

Memory layout example based on my PXA255 (TEXT_BASE = 0xA07E0000):
0xA079FF74   Monitor Stack (growing downwards)
0xA079FF80   Board Info Data and permanent copy of Global Data
0xA07A0000   Malloc Arena
0xA07E0000   RAM copy of Monitor Code
...          optional: Frame Buffer
0xA07FFFFF   [End of RAM]
The ordering of the blocks in the above memory map is only valid with
my patch applied.

TEXT_BASE determines the start address in FLASH memory which is  used
before relocation.

Now is TEXT_BASE the "address in FLASH memory" or the address of the "RAM
copy 
of Monitor Code"???
For ARM, TEXT_BASE refers to the RAM copy;
for all other architectures TEXT_BASE refers to FLASH.
