I am using SPI Hook to flash the u-boot.rom. In the SPI Hook log , I
am seeing that the flash driver is Winbond and not STMICRO,

flashrom v0.9.8-r1888 on Linux 3.11.0-26-generic (x86_64)
flashrom is free software, get the source code at http://www.flashrom.org

Calibrating delay loop... OK.
Found Winbond flash chip "W25Q64.V" (8192 kB, SPI) on ft2232_spi.

Then I should enable CONFIG_SPI_FLASH_WINBOND and not
CONFIG_SPI_FLASH_STMICRO right??
