[PATCH 0/8] binman: Enhancements for symbol handling

[Simon Glass]

A recent U-Boot discussion[1] yielded a suggestion to allow an entry to be
positioned by an ELF symbol.

A similar need has come up in ChromiumOS' use of Zephyr[2], this time with
an additional offset added in.

This series adds support for this along with a few other things:

- Generic support for updating ELF symbols (such that it can be used by
  Zephyr)
- Support for 'null' entries which have no contents, but do appear in the
  fdtmap or FMAP
- Support for overlapping entries
