; @Title: SPI(Serial NOR) Flash Program script for LX2160A
; @Description:
; The 2ea MT35XU512ABA1G12(Micron) are connected serially to the FLEXSPI_A
; controller ( XSPI1_A_CS0_B, XSPI_CS1_A_CS1_B, XSPI_A_SCK, XSPI_A_D[0:7] )
;
; SRAM: 0x18010000
; FlexSPI(controller) Base: 0x20c0000
;
; Prerequisites:
; * connect Debug Cable/Combiprobe to J11 JTAG using LA-3770
;
;
; @Keywords: ARM, Cortex-A72, LX2160A, QorIQ, FlexSPI

; temporarily override the RCW. The RCW is fetched while the boot phase and defines initial
; pinmux/serdes/qspi/nor/nand/... configurations.
; The RCW override requires to reset the SoC. Two methods are supported.
; Method 1: EnReset OFF && HRCWOVerRide ON /PORESET - do not assert the nReset line, issue a JTAG based PORESET
; Method 2: EnReset ON && HRCWOVerRide ON - assert the nReset line
; Steps - Override RCW completely
