It's not CFI compliant. But you can use the legacy infrastructure in this driver, which meant to support such chips. Please take a look at the following driver: drivers/mtd/jedec_flash.c Your board config header would need something like this: /* Use common CFI driver */ #define CONFIG_SYS_FLASH_CFI #define CONFIG_FLASH_CFI_DRIVER /* board provides its own flash_init code */ #define CONFIG_FLASH_CFI_LEGACY 1 #define CONFIG_SYS_FLASH_CFI_WIDTH FLASH_CFI_8BIT #define CONFIG_SYS_FLASH_LEGACY_512Kx8 1 ... Taken from include/configs/hcu4.h. This should give you an idea...
