[U-Boot-Users] bad flash write times with u-boot

The cfi_flash.c driver and CFG_FLASH_USE_BUFFER_WRITE did the trick.
Performance is much better.   We had been using a different flash driver.

Thanks much.

Make sure you are using the common cfi_flash.c driver and
CFG_FLASH_USE_BUFFER_WRITE is set.  If you are still having problems,
I can benchmark my system here.
