- help
- This enables support for Fast Early Loader (FEL) mode. This
- allows U-Boot to be loaded to the board over USB by the on-chip
- boot rom. U-Boot should be sent in two parts: SPL first, with
- 'fel write 0x2000 u-boot-spl.bin; fel exe 0x2000' then U-Boot with
- 'fel write 0x4a000000 u-boot.bin; fel exe 0x4a000000'. This option
- shrinks the amount of SRAM available to SPL, so only enable it if
- you need FEL. Note that enabling this option only allows FEL to be
- used; it is still possible to boot U-Boot from boot media. U-Boot
- SPL detects when it is being loaded using FEL.
