RE: QSPI_FLASH_ISSUE

Where did you define CONFIG_SYS_NO_FLASH in your file ?

Somewhere in your file you should have something like :

/* NOR Flash */

#ifndef CONFIG_SYS_NO_FLASH

#define CONFIG_SYS_FLASH_BASE 0x00000000

#define CONFIG_SYS_MAX_FLASH_BANKS 1

#define CONFIG_SYS_MAX_FLASH_SECT 512

#define CONFIG_FLASH_CFI_DRIVER

#define CONFIG_SYS_FLASH_CFI

#define CONFIG_SYS_FLASH_CFI_WIDTH FLASH_CFI_16BIT

#define CONFIG_SYS_FLASH_BANKS_LIST { CONFIG_SYS_FLASH_BASE }

#define CONFIG_SYS_MONITOR_BASE CONFIG_SYS_FLASH_BASE

#endif

So you need to ensure CONFIG_SYS_NO_FLASH is defined before this part.

I tried to build rskrza1 U-boot-2015.01 from  Renesas git repository with CONFIG_SYS_NO_FLASH, I didn't get any error.
