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.
