- 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:
- 'Access to binman entry offsets at run time (symbols)'
- 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.
