; @Title: OSPI FLASH Program script for the G9H (SemiDrive)
; @Description:
; The OSPI flash is connected to the OSPI1_CS0 controller.
; Supported OSPI1 flash memories:
; - MT35XU256
; OSPI1_DATA[0:7] - DQ[0:7]
; OSPI1_DQS - DQS
; OSPI1_SCLK - CK
; OSPI1_SS0 - CS1
; OSPI1_RST_N(GPIO_B5) - RESET
;
; SRAM:
; OSPI(controller) Base: 0xF0020000
; OSPI memory mapped ADDRESS: 0x04000000
;
; @Keywords: ARM, Cortex-R5
; @Chip: G9090
