Added CONFIG_ options for bd_t and env in flat dev tree
Signed-off-by: Kumar Gala galak@kernel.crashing.org
CHANGELOG: * Added CONFIG_ options for bd_t and env in flat dev tree
CONFIG_OF_HAS_BD_T will put a copy of the bd_t into the resulting flat device tree.
CONFIG_OF_HAS_UBOOT_ENV will copy the environment variables from u-boot into the flat device tree
