RFC: raw extcsd dump

[Grant Grundler]

Chris,
Are you interested in "raw dump" of extcsd data?

We need it to dump vendor specific data that happens to be in a reserved field.

Chromium.org code review is here:
   https://chromium-review.googlesource.com/#/c/189002/

git magic to pull that patch is here:
   git pull https://chromium.googlesource.com/chromiumos/third_party/mmc-utils
refs/changes/02/189002/4

I can also post the patch as normal inline if you are interested.

cheers
grant

I don't see any reason to exclude it from mmc-utils, but have you seen
the debugfs node?

mount -t debugfs /dev/mmcblk0 /mnt/
cat /mnt/mmc0/mmc0\:0001/ext_csd

Want to explain whether that's insufficient?  If so, maybe we should
just fix that instead.

Thanks,

- Chris.
