Exynos Snow and Peach Pit/Pi Chromebooks have a serial dataflash that
is accessed through SPI. This series add spidev nodes in the Device
Tree source files so the flash can be accessed from user-space.

The series is composed of the following patches taken from the ChromeOS tree:

Doug Anderson (1):
  ARM: dts: Add spidev registration to exynos5250-snow

Javier Martinez Canillas (1):
  ARM: exynos_defconfig: Enable user mode SPI device support

Simon Glass (1):
  ARM: dts: Add SPI flash node for Peach boards

Patch #1 adds the spidev node for the Snow Chromebook, patch #2
adds the spidev node for Peach Chromebooks and peach #3 enables
support for the user mode SPI device driver.

The series were tested on Snow and Peach using:

$ flashrom -p linux_spi:dev=/dev/spidev1.0 --get-size
$ flashrom -p linux_spi:dev=/dev/spidev1.0 --flash-name

and verify that the flash can be accessed

$ set_gbb_flags 0x39

and verify that the GBB flags could be written.

Best regards,
Javier
