Hi Philipp,

This introduces the ability to override the environment offets from the device tree by setting the following nodes in '/config': 'u-boot,mmc-env-offset' - overrides CONFIG_ENV_OFFSET 'u-boot,mmc-env-offset-redundant' - overrides CONFIG_ENV_OFFSET_REDUND
To keep with the previous logic, the CONFIG_* defines still need to be available and the statically defined values become the defaults, when the corresponding properties are not set in the device-tree.

I'm doing check this patches..after building,,if there is no problem, i will pick.
Applied to u-boot-mmc. Thanks!

Thanks!

Changes in v4:
- change the test for OF_CONTROL to use CONFIG_IS_ENABLED to pick up the differece between SPL_OF_CONTROL and OF_CONTROL
Changes in v3:
- changes the config-check to depend on CONFIG_OF_CONTROL to detect if 'fdtdec_get_config_int' is available
Changes in v2: None
