[PATCH 0/3] spi-nor: Add support for Intel SPI serial flash controller

[Mika Westerberg]

Hi,

This series adds support for the Intel SPI serial flash controller found on
many recent Intel CPUs including Baytrail and Braswell. This driver makes
it possible to access the BIOS and other platform data which is stored on
the SPI serial flash. It is also possible to upgrade the BIOS using this
driver if it has not been protected by special hardware bits.

The patch [1/3] includes documentation how to upgrade BIOS on MinnowBoard
MAX.

Since poking the SPI serial flash can brick the machine, this driver can
only be enabled when CONFIG_EXPERT=y and even then it will remain read-only
unless instructed othwerwise by module parameter.
