[PATCH 00/12] arm: xea: Provide support for different XEA board HW versions

[Lukasz Majewski]

This patch set provides support for different XEA board revisions.
Due to very limited SPL size, the board's switch DTB decision is
performed very early in u-boot proper; before driver model is set.

Adjustments for DTS between revisions are for the u-boot adjustment code
(i.e. tweaks due to functionality not supported in u-boot), hence
there is no need to update them from Linux upstream DTS.


Lukasz Majewski (12):
  arm: spl: xea: Remove I2S pins configuration from early initialization
  arm: xea: Add support for reading SoM (CPU) and base board HW revision
  arm: xea: Rename imx28-xea.dts to imx28-xea-1.dts
  dts: xea: Move phy-reset-gpios property to version specific DTS file
  dts: xea: Remove outdated comment
  arm: xea: Add support for multiple dtbs in u-boot
  dts: xea: Add device tree description for XEA HW rev. 2
  arm: spl: Add definition for PHY reset GPIO for XEA HW rev. 2
  arm: config: xea: Enable support for multiple DTBs for XEA board
  config: xea: Enable late board initialization to set revision variable
  arm: xea: Print information about XEA's SoM HW revision
  arm: env: Add support for booting different HW revisions of XEA boards
