640 bool "Support an environment"
Simon Glass1e3911a2016-09-13 07:05:23 -0600641 help
642 Enable environment support in SPL. The U-Boot environment provides
643 a number of settings (essentially name/value pairs) which can
644 control many aspects of U-Boot's operation. Normally this is not
645 needed in SPL as it has a much simpler task with less
646 configuration. But some boards use this to support 'Falcon' boot
647 on EXT2 and FAT, where SPL boots directly into Linux without
Simon Glass64b723f2017-08-03 12:22:12 -0600648 starting U-Boot first. Enabling this option will make env_get()
Simon Glass6a38e412017-08-03 12:22:09 -0600649 and env_set() available in SPL.
