; @Title: SPI FLASH Program script for the MSR1(STA800C)
;
; @Description:
; The MT25QU128 (Micron) is connected to the SQIO controller
;
; SRAM:                       0x20001000 (TCM 64KB)
; SQIO(controller)   Base:    0x51000000
; SQIO memory mapped ADDRESS: 0x50000000 (only 16MB mapped, Alias 0x88000000)
;
; GPIOE_4[0]   FLASH_QSPI_D0
; GPIOE_4[1]   FLASH_QSPI_D1
; GPIOE_4[2]   FLASH_QSPI_D2
; GPIOE_4[3]   FLASH_QSPI_D3
; GPIOE_4[4]   GPIO70
; GPIOE_4[5]   GPIO71
; GPIOE_4[6]   GPIO72
; GPIOE_4[7]   GPIO73
; GPIOE_4[8]   FLASH_QSPI_CS
; GPIOE_4[9]   FLASH_QSPI_CLK
;
; Script arguments:
;
;    DO msr1-spi [PREPAREONLY] [CPU=<cpu>] [DUALPORT=0|1]
;
;      PREPAREONLY only declares flash but does not execute flash programming
;
;      CPU=<cpu> selects CPU derivative <cpu>
;
;      DUALPORT=0|1 default value is 0 (disabled).
;
;   Example:
;
;   DO ~~/demo/arm/flash/msr1-spi.cmm PREPAREONLY DUALPORT=1
