[MrCry0]

This fixes #1

This backported commit adds support of option "-m" missing in the initially imported utility.

Fixes: 7586c81 ("Import gen_partition.py utility")

Changes tested by generating xml scheme from live qcm6490-partitions.conf.

Can you please add the signed-off tag of the original author?

Also, while you are at it.. can you add a patch that describes better what this mapping command does? perhaps provide an example of the mapping file, so that users don't need to read the code to learn how to use it? Documenting inline should be fine for now.

The -m option is already documented in Usage:

$ ./gen_partition.py 

	Usage: ./gen_partition.py -i <input> -o <output> -m [partition_name1=image_filename1,partition_name2=image_filename2,...]
	Version 1.0

It maps partitions from the input config file to alternative image files - it is useful if one needs to use an original config file replacing few or even one partition source.
Let me know if you think it's not enough and I'll add a better description, may be with an example of usage.
