* Memory layout notes:
* ====================
*
* IAR Default Memory layout notes:
* -Heap defined by "HEAP" region in .icf file
* -Interrupt stack defined by "CSTACK" region in .icf file
* -Value INITIAL_SP is ignored
* IAR Memory layout :
* - Heap defined by "HEAP" region in .icf file
* - Interrupt stack defined by "CSTACK" region in .icf file
* - Value INITIAL_SP is ignored
*
* IAR Custom Memory layout notes:
* -There is no custom layout available for IAR - everything must be defined in
* the .icf file and use the default layout
* GCC Memory layout :
* - Heap explicitly placed in linker script (*.ld file) and heap start (__end___) and heap end (__HeapLimit) should be defined in linker script
* - Interrupt stack placed in linker script **.ld file) and stack start (__StackTop) and stack end (__StackLimit) should be defined in linker script
*
*
* GCC Default Memory layout notes:
* -Block of memory from symbol __end__ to define INITIAL_SP used to setup interrupt
* stack and heap in the function set_stack_heap()
* -ISR_STACK_SIZE can be overridden to be larger or smaller
*
* GCC Custom Memory layout notes:
* -Heap can be explicitly placed by defining both HEAP_START and HEAP_SIZE
* -Interrupt stack can be explicitly placed by defining both ISR_STACK_START and ISR_STACK_SIZE
*
*
* ARM Memory layout
* -Block of memory from end of region "RW_IRAM1" to define INITIAL_SP used to setup interrupt
* stack and heap in the function set_stack_heap()
* -ISR_STACK_SIZE can be overridden to be larger or smaller
*
* ARM Custom Memory layout notes:
* -Heap can be explicitly placed by defining both HEAP_START and HEAP_SIZE
* -Interrupt stack can be explicitly placed by defining both ISR_STACK_START and ISR_STACK_SIZE
* ARM Memory layout :
* - Heap can be explicitly placed by adding ARM_LIB_HEAP section in scatter file and defining both HEAP_START and HEAP_SIZE
* - Interrupt stack placed in scatter files (*.sct) by adding ARM_LIB_STACK section
