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.

1335 Enable support for using SPI in SPL. This is used for connecting
1336 to SPI flash for loading U-Boot. See SPL_SPI_FLASH_SUPPORT for
1337 more details on that. The SPI driver provides the transport for
1338 data between the SPI flash and the CPU. This option can be used to
1339 enable SPI drivers that are needed for other purposes also, such
