[U-Boot] [PATCH 01/05] env: enable accessing the environment in an EXT4 partition
From: Jorge Ramirez-Ortiz jorge.ramirez-ortiz@linaro.org
For example to store the environment in a file named "/uboot.env" in MMC "0", where partition "1" contains the EXT4 filesystem, the following configs should be added to the board's default config:
CONFIG_ENV_IS_IN_EXT4=y CONFIG_ENV_EXT4_DEVICE_AND_PART="0:1" CONFIG_ENV_EXT4_FILE="/uboot.env" CONFIG_ENV_EXT4_INTERFACE="mmc"
