[PATCH 0/4] crypto: Add new UCLASS_HASH

[Chia-Wei Wang]

This patch series proposes new UCLASS_HASH for hash devices.
Thus the hash drivers (SW or HW-accelerated) can be developed
in the DM-based fashion.

A purely software implemented hash driver is also added under
the newly added UCLASS_HASH uclass. In addition, the FIT image
hash verification is also updated to leverage the UCLASS_HASH
driver if configured.

As there is widly spread use of non-DM hash functions (common/hash.c),
this patch does not remove them. More patches are needed if UCLASS_HASH
is established.

Chia-Wei Wang (4):
  lib/md5: Export progressive APIs
  dm: hash: Add new UCLASS_HASH support
  crypto: hash: Add software hash DM driver
  fit: Use DM hash driver if supported
