641 a number of settings (essentially name/value pairs) which can
642 control many aspects of U-Boot's operation. Normally this is not
643 needed in SPL as it has a much simpler task with less
644 configuration. But some boards use this to support 'Falcon' boot
645 on EXT2 and FAT, where SPL boots directly into Linux without

1333 Enable support for using SPI in SPL. This is used for connecting
1334 to SPI flash for loading U-Boot. See SPL_SPI_FLASH_SUPPORT for
1335 more details on that. The SPI driver provides the transport for
1336 data between the SPI flash and the CPU. This option can be used to
1337 enable SPI drivers that are needed for other purposes also, such
1338 as a SPI PMIC.
