"""TPL binary without device tree appended
Properties / Entry arguments:
- filename: Filename to include (default 'tpl/u-boot-tpl-nodtb.bin')
This is the U-Boot TPL binary, It does not include a device tree blob at
the end of it so may not be able to work without it, assuming TPL needs
a device tree to operate on your platform. You can add a u-boot-tpl-dtb
entry after this one, or use a u-boot-tpl entry instead (which contains
both TPL and the device tree).
TPL 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 'tpl/u-boot-tpl' must also be available for this to work, since
binman uses that to look up symbols to write into the TPL binary.
