[U-Boot] [PATCH 25/34] binman: Allow support for writing a size symbol to binaries

[sjg at google.com]

It is useful to be able to access the size of an image in SPL, with
something like:

binman_sym_declare(unsigned long, u_boot_any, size);

...
   ulong u_boot_size = binman_sym(ulong, u_boot_any, size);

Add support for this and update the tests.
