[U-Boot] [PATCH v2] ARM: mx6: Add support for Kosagi Novena

Marek Vasut marex at denx.de
Sat Sep 6 19:22:32 CEST 2014 

Add support for the Kosagi Novena board. Currently supported are:
- I2C busses
- FEC Ethernet
- MMC0, MMC1, Booting from MMC
- SATA
- USB ports
- USB Ethernet

V2: - Drop the tegra_keyboard_init() comment altogether
    - Immediatelly return from the SD controller probe function on failure
    - Rename PFUZE100_PMIC to just PFUZE100
    - Fix the IMX OTP support with CMD_FUSE
    - Enabling LVDS clock is still in place, since this is coming soon.
