[PATCH 06/10] binman: Support finding symbols in sub-sections

[Simon Glass]

At present binman only supports resolving symbols in the same section as
the binary that uses it. This is quite limited because we often need to
group entries into different sections.

Enhance the algorithm to search the entire image for symbols.
