By default saveenv option is not supported for SPL. This patch enable the support for save environment variable for SPL build. Enable save environment support in SPL after setenv. By default the saveenv option is not provided in SPL, but some boards need this support in 'Falcon' boot, where SPL need to boot from different images based on environment variable set by OS. For example OS may set "reboot_image" environment variable to "recovery" inorder to boot recovery image by SPL. The SPL read "reboot_image" and act accordingly and change the reboot_image to default mode using setenv and save the environemnt. Signed-off-by: Ravi Babu <ravibabu@ti.com> Reviewed-by: Simon Glass <sig@chromium.org> change in v1: - dropped SUPPORT, use CONFIG_SPL_SAVEENV - updates the comments in mmc_private.h
