Hi Vignesh,
BIOS just locked down parts of flash (such as, code region), others are still
writeable. Once the SPI locked down,it can't be override unless platfrom reset
and set WPD (write protect disable) will fail, so ispi->writeable will always
be 0,

This option currently doesn't work as expected. If the BIOS has this
flash as read-only there is no way to change this thru the driver.
There is a parameter which allows the flash to become writable with the
"writable" option to the module, but it does nothing if the BIOS has it
set to read-only.
