; @Title: Generic script for Freescale MKL43 and MKL46 internal flash
;
; @Description:
;
; Example for flash declaration of Freescale MKL43 and MKL46 internal
; flash.
;
; Script arguments:
;
;   DO mkl40 [PREPAREONLY] [CPU=<cpu>] [DUALPORT=0|1] [MASSERASE]
;
;     PREPAREONLY only declares flash but does not execute flash programming
;
;     CPU=<cpu> selects CPU derivative <cpu>
;
;     DUALPORT default value is 0 (disabled). If DualPort mode is enabled
;             flash algorithm stays running until flash programming is
;             finished. Data is tranferred via dual port memory access.
;
;     MASSERASE forces mass erase of device before establishing debug connection
;
; For example:
;
;   DO ~~/demo/arm/flash/mkl40 CPU=MKL46Z256VMC4 DUALPORT=1 PREPAREONLY
;
; List of MKL43 and MKL46 derivatives and their configuration:
