"""Look up a symbol in an ELF file
Looks up a symbol in an ELF file. Only entry types which come from an
ELF image can be used by this function.
- At present the only entry property supported is offset.
+ At present the only entry properties supported are:
+ offset
+ image_pos - 'base_addr' is added if this is not an end-at-4gb image
+ size
Args:
sym_name: Symbol name in the ELF file to look up in the format
optional: True if the symbol is optional. If False this function
will raise if the symbol is not found
msg: Message to display if an error occurs
+ base_addr: Base address of image. This is added to the returned
+ image_pos in most cases so that the returned position indicates
+ where the targetted entry/binary has actually been loaded. But
+ if end-at-4gb is used, this is not done, since the binary is
+ already assumed to be linked to the ROM position and using
+ execute-in-place (XIP).
Returns:
Value that should be assigned to that symbol, or None if it was
