;
; This scatterloading descriptor file defines: one load region (ROM_LOAD) 
; and five execution regions (ROM_EXEC, RAM, HEAP, STACKS, UART0).
;
; The entire program (code & data) is placed in ROM at ROM_LOAD.
;
; The RO code will execute from ROM_EXEC.  Its execution address (0x0) is the same
; as its load address (0x0), so it does not need to be moved (a 'root region').
; The exception vector table (AREA Vect in vectors.s) must appear at 0x0, so is 
; placed '+First' in the image.
;
; The RW data will get relocated (copied) from ROM_LOAD to RAM at 0x28000000.
; The ZI data will get created (initialized) in RAM, above the RW data.
;  
; The region HEAP is used to locate the bottom of the heap immediately above 
; the ZI data ("+0"). The heap will grow up from this address.
;
; The region STACKS is used to locate the top of the memory used to store
; the stacks for each mode. The stacks will grow down from this address.
;
; The region UART0 is used to map the position of the Integrator UART0 registers.
;
; Regions marked UNINIT will be left uninitialized, i.e. they will not be 
; zero-initialized by the C library when it starts-up.
