The documentation states that SPL is enabled in all config options for the da850. This incorrect, because devices booting from NOR do not need the SPL to do the low level initializion because when booting from NOR, the board is able to execute in place (XIP)

This also clarifies that SPL isn't only used for booting from SPI, because it is also used for booting from MMC and NAND for those devices supporting those boot options.
