Cover letter [PATCH v3 0/6] Basic inline encryption support for ufs-exynos
Add support for Flash Memory Protector (FMP), which is the inline encryption hardware on Exynos and Exynos-based SoCs.
Specifically, add support for the "traditional FMP mode" that works on many Exynos-based SoCs including gs101. This is the mode that uses "software keys" and is compatible with the upstream kernel's existing inline encryption framework in the block and filesystem layers. I plan to add support for the wrapped key support on gs101 at a later time.
Tested on gs101 (specifically Pixel 6) by running the 'encrypt' group of xfstests on a filesystem mounted with the 'inlinecrypt' mount option.
This patchset applies to v6.10-rc6, and it has no prerequisites that aren't already upstream.
Changed in v3:
- Made the FMP support depend on EXYNOS_UFS_OPT_UFSPR_SECURE, since the !EXYNOS_UFS_OPT_UFSPR_SECURE case has not yet been tested
- Replaced LOG2_DATA_UNIT_SIZE with ilog2(DATA_UNIT_SIZE)
- Added Reviewed-by tags
Changed in v2:
- Added DATA_UNIT_SIZE macro
- Changed a comment into kerneldoc
- Used ARM_SMCCC_CALL_VAL() to define SMC codes
- Used arm_smccc_smc() directly instead of via a wrapper function
