Hi, all:
I am trying to boot 'u-boot' on a new board by I got the following
message in flash_init(), i.e. flash_init() return failure.
I am using the ../u-boot/drivers/cfi_flash.c, is it correct ? Or I
have to write my own flash_init() etc. In flash_detect_cfi()
funtion, u-boot can't detect the infomation of the flash, and the
flash on my board is TE28F256J3C-125, in 8 bits data
bus width.
FS-BOOT: System initialisation completed.
FS-BOOT: No existing image in FLASH. Starting image download.
FS-BOOT: Waiting for SREC image....

FS-BOOT: Warning image location differ from default boot location.
Image will not boot automatically after POR.
