; @Title: Generic script for Freescale MKW20,MKW21,MKW22 and MKW24 internal flash
;
; @Description:
; Flash declaration of NXP MKW20Z/MKW21Z/MKW21D/MKW22D/MKW24D internal flash.
; Script arguments:
; DO mkw20 [PREPAREONLY] [CPU=<cpu>] [MASSERASE]
; PREPAREONLY only declares flash but does not execute flash programming
; CPU=<cpu> selects CPU derivative <cpu>
; DUALPORT=<0|1> use dual port memory access, default 1
; MASSERASE forces mass erase of device before establishing debug
; connection
; Example:
;
; DO ~~/demo/arm/flash/mkw20 CPU=MKW21D256VHA5 PREPAREONLY
;
; List of MKW21/MKW22/MKW24 derivatives and their configuration:
