; @Title: Example for flash declaration of NXP LPC43xx external QSPI flash 
;
; @Description: 
; Example for flash declaration of NXP LPC43xx external QSPI flash connected
; via SPIFI interface.
; Script arguments:
;
;   DO lpc43xx-qspi [PREPAREONLY] [CPU=<cpu>] [QSPI=<flashdevice>] [DUALPORT=0|1]
;
;     PREPAREONLY only declares flash but does not execute flash programming
;
;     CPU=<cpu> selects CPU derivative <cpu>
;
;     QSPI=<flashdevice> declares flash sectors depending on QSPI flash device
;
;     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. 
;
; For example:
;
;   DO ~~/demo/arm/flash/lpc43xx-qspi CPU=LPC4357FET256 QSPI=S25FL032P1F 
;                                      DUALPORT=1 PREPAREONLY
;
; Memories:
;
;   SPIFI memory is mapped to         0x80000000--0x87FFFFFF
;     and lower half of range also to 0x14000000--0x17FFFFFF
;   32 kB local SRAM is located at    0x10000000
;
; HINTS:
;
;   Flash clock has to match SPIFI Clock Frequency. Example script is using
;   12 MHz IRC oscillator.
