[RFC PATCH 00/10] crypto: caam - add DPAA2 (DPSECI) driver

[Horia Geantă]

Hi,

This patch set adds the CAAM crypto engine driver for DPAA2
(Data Path Acceleration Architecture v2) found on ARMv8-based SoCs
like LS1088A, LS2088A.

Driver consists of:
-DPSECI (Data Path SEC Interface) backend - low-level API that allows
to manage DPSECI devices (DPAA2 objects) that sit on
the Management Complex (MC) fsl-mc bus
-algorithms frontend - AEAD and ablkcipher algorithms implementation

Patches 1-4 include DPIO object dependencies.
I am aware that DPIO is currently in staging, however I don't consider
these to be a large feature set. Anyhow, please let me know if going
with the patches through staging is acceptable.

Patches 5-9 are the core of the patch set, adding the driver.
For symmetric encryption the legacy ablkcipher interface is used; the
plan is to convert to skcipher all CAAM frontends at once at a certain
point in time.

Patch 10 enables driver on arm64. It will be built only if dependency
on DPIO (CONFIG_FSL_MC_DPIO) is satisfied.

Thanks,
Horia
