+The code that picks the location in RAM for ARM can be found in the 
+arch/arm/lib/board.c file under the board_init_f function. 
+The postfix _f means executed from flash, and _r means from RAM. 
+The new location is picked with respect to the highest RAM address, and the
+exact final value depends heavily on compile time options. The source is the
