[PATCH v3] bmap: generate bmap for wic images

[Daniel Sangorrin]

bmap shortens the time required to flash an image.
This can be useful when you need a fixed-size image, for
example to update partitions with swupdate.

Example usage:
sudo bmaptool copy --bmap \
build/tmp/deploy/images/iwg20m/cip-core-image-cip-core-iwg20m.wic.img.bmap \
build/tmp/deploy/images/iwg20m/cip-core-image-cip-core-iwg20m.wic.img \
/dev/sdf

[PATCH v3] bmap: generate bmap for wic images

[daniel.sangorrin]

Hi all,

It seems the patch below didn't get into ISAR.
#Probably because I posted other patches for the isar-cip-core layer, and that created confusion. Sorry^^.

Thanks,
Daniel

Applied to next, thanks.

Would you like to add a brief section on motivation and usage to the user
manual?

With kind regards,
