Eric Biggers <ebiggers@kernel.org> says: 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. Link: https://lore.kernel.org/r/20240708235330.103590-1-ebiggers@kernel.org Signed-off-by: Martin K.
