-This patch adds support for CFG_ENV_OFFSET_PATCHED and
-CFG_ENV_OFFSET_OOB.
-
-Both try to solve the problem of fixing the environment location in NAND flash
-at compile time, which doesn't work well if the NAND flash has a bad block at
-exactly that location.
-
-CFG_ENV_OFFSET_PATCHED puts the environment in a global variable. You can then
-use the linker script to put that variable to a fixed location in the u-boot
-image. Then you can use bianry patching during the production flash process.
-
-The idea of CFG_ENV_OFFSET_OOB is to store the environment offset in the NAND
-OOB data of block 0. We can do this in case the vendor makes a guarantee that
-block 0 never is a factory-default bad block.
