| This is the U-Boot SPL binary, It does not include a device tree blob at |
| the end of it so may not be able to work without it, assuming SPL needs |
| a device tree to operate on your platform. You can add a u-boot-spl-dtb |
| entry after this one, or use a u-boot-spl entry instead' which normally |
| expands to a section containing u-boot-spl-dtb, u-boot-spl-bss-pad and |
| u-boot-spl-dtb |
| |
| SPL can access binman symbols at runtime. See :ref:`binman_fdt`. |
| |
| in the binman README for more information. |
| |
| The ELF file 'spl/u-boot-spl' must also be available for this to work, since |
| binman uses that to look up symbols to write into the SPL binary. |
