How to extract PStore from a device with mtkclient

This must be done after a kernel panic/warm boot. Otherwise you might not get any meaningful data.
The first two steps can be skipped if you know the address and the length of the region.

Extract expdb partition and run the strings against the image.

$ python mtk.py r expdb expdb.img

This error might occur durring kernel build. It is happening because newer versions of OpenSSL disallow using SHA-1.
