;
; This scatterloading descriptor file defines: one load region (ROM_LOAD) 
; and five execution regions (ROM_EXEC, RAM, HEAP, STACKS, ISR_STARTADDRESS).
;
; The entire program (code & data) is placed in ROM_EXEC which resides 
; at 0xc080000, of length 1.5Mbytes.  Program execution starts at AREA
; Init in init.s, which is placed '+First' in the image. Following reset, 
; the first few instructions of init.s.
;
; RAM might be fast on-chip (internal) RAM, and is typically
; used for the stack and code that must be executed quickly.

; 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 ISR_STARTADDRESS is used to map the position of the 
; interrupts.
;
; Regions marked UNINIT will be left uninitialized, i.e. they will not be 
; zero-initialized by the C library when it starts-up.
