Subject: [PATCH v2 00/26] pstore, mmc: add mmc as backend for pstore
From: Dragos Tatulea <dragos.tatulea@...el.com>
These patches enable using the mmc card to store panic information.
They include changes for pstore and mmc:
- add block device backend for pstore
- add logic in mmc for writing in panic mode
A mmc host driver must implement mmc_panic_ops. This patchset contains
an implementation for sdhci.
v2:
- Added some detailed description to some commits. Not all of them
though because they are very small and self explanatory.
- Added clarification on what mmc host controller drivers have to
implement to support panic dumping.
