[v7,0/3] crypto: Add EIP-93 crypto engine support

Message

Christian Marangi Nov. 12, 2024, 1:58 a.m. UTC

This small series add support for the Inside Secure EIP-93.
This is a predecessor of the current supported EIP197. It doesn't
require a firmware but instead it's embedded in the SoC.

First patch extend guard for spinlock_bh.

The other actually implement Documentation and Driver.

The Driver pass all the normal selft test for the supported
algo and also pass the EXTRA test with fuzz_iterations set to 10000.

Changes v7:
- Fix copypaste error in __eip93_hash_init
- Rework import/export to actually export the partial hash
  (we actually unmap DMA on export)
- Rename no_finalize variable to better partial_hash
- Rename 3rd commit title and drop Mediatek from title.
- Add Cover Letter
- Add Reviewed-by to DT commit
(cumulative changes from old series that had changelog in each patch)
Changes v6:
- Add SoC specific compatible
- Add now supported entry for compatible with no user
Changes v5:
- Add Ack tag to guard patch
- Comment out compatible with no current user
- Fix smatch warning (reported by Dan Carpenter)
Changes v4:
- Out of RFC
- Add missing bitfield.h
- Drop useless header
Changes v3:
- Mute warning from Clang about C23
- Fix not inizialized err
- Drop unused variable
- Add SoC compatible with generic one
Changes v2:
- Rename all variables from mtk to eip93
- Move to inside-secure directory
- Check DMA map errors
- Use guard API for spinlock
- Minor improvements to code
- Add guard patch
- Change to better compatible
- Add description for EIP93 models
