mmc-utils: Initial contribute of lsmmc

Dear all,

this is a release to the community of the source code of the utility
"lsmmc", created by Sebastian Rasmussen formerly at ST-Ericsson.

lsmmc contains an extensive parser of the CID, CSD, SCR and EXT_CSD
registers, as well as an archive of these registers for over 120
eMMC and SD-cards. The utility works as-is and uses sysfs to read the
register values.

It could be a candidate for incorporation into the mmc-utils, but it
naturally requires some adaptation. Please consider this code to be at
your disposal.

Chris: I decided that a .tar.gz was more tasteful in the end, the patch
whould have contained lines > 1000 chars and been 8000 lines long ;)

Kind regards, Johan

Attachment (lsmmc.tar.gz): application/x-gzip, 32 KiB

FYI, some work has been already done (and reviewed by Sebastian); take a
look at

Yes, I've seen this contribution, and I think that the lsmmc code can
be used to further extend this work!

Kind regards, Johan

Excellent, I'll take a look at adapting this for mmc-utils
and have cjb review it soonish as promised. Midsummer
nights eve is coming right up, so I'll have a few hours of
spare time. :) Thanks Johan for prodding legal until they
approved the release.
