; @Title: R-CarV4H for R8A779G-CR52 on WhiteHawk QSPI Flash script
; @Description:
; SPI FLASH Program script by the core (CR52) for the Evaluation
; The S26KS512SDPBHV02(U26) is on the SPI Multi I/O Bus controller (RPC-IF)
;
;   Prerequisites:
;    * Cortex-R52 boot
;        MD6 = 1 (SW1[1] = OFF)
;        MD7 = 1 (SW1[2] = OFF)
;    * QSPI boot mode (HyperFlash ROM boot at 160 MHz (320 Mbps) using DMA)
;        MD4 = 0 (SW1[5] = ON)
;        MD3 = 0 (SW1[6] = ON)
;        MD2 = 1 (SW1[7] = OFF)
;        MD1 = 0 (SW1[8] = ON)
;
;    * activate S25FS512 flash
;        SW13 = x: on/off don't matter
;        SW57 = 1: HyperFlash(U26)
;
; SRAM: 0xE6328000
; SPI Multi I/O Bus(controller) Base: 0xEE200000
