[PATCH v3 0/2] drm/xe/nvm: add survivabilty partiton

[Alexander Usyskin]

One of the reasons for the CRI to enter survivability mode
is corrupted storage.
A corrupted storage partition table can make recovery impossible.
A new partition with a pre-defined size, covering the entire storage,
should replace partitions detected from the storage when the card is
in survivability mode to allow a full memory update.

This series intended to be merged via drm tree for consistency
and requires ack from MTD maintainer.

Changes in v3:
- Fix minor checkpatch complain
- Add Miquel ack
- Link to v2: https://lore.kernel.org/r/20260916-cri_surviv-v2-0-7de1b5328204@intel.com

Changes in v2:
- Replace usual partitions with survivability one instead of adding
  addition partition to avoid problems with two partitons pointing to
  the same memory area.
- The change is in the mtd part; Miquel, I feel that this requires
  re-review/ack from your side.
- Link to v1: https://lore.kernel.org/r/20260715-cri_surviv-v1-0-61763a6f1076@intel.com
