I will try to add a patch. Actually, I have implemented it on allwinner
platform, but unfortunately these codes are unsuitable to submit to
upper stream.

In addition, there is already a sample for pstore/blk on patch 3 of
version 7. It names
blkoops. Blkoops is suitable for most block device as what it need is
just a path of a partition. We can use it to test most of features but
panic.
