; @Title: Example for flash declaration of EnergyMicro EFM32 Tiny Gecko internal flash.
;
; @Description: 
; Script arguments:
;
;   DO efm32tg [PREPAREONLY]
;
;     PREPAREONLY only declares flash but does not execute flash programming
;
;     CPU=<cpu> selects CPU derivative <cpu>
; Example:
; List of EFM32 Tiny Gecko derivatives and their configuration:
;
;   CPU                             FlashSize  RamSize
;   Derivative       CpuType           [kB]      [kB]
