[PATCH v4 0/4] crypto: add precalculated hash for zero message length

[LABBE Corentin]

Hello

Some crypto drivers cannot process empty data message and so rely on
precalculated hash.
This patch series add precalculated hash in headers and
make the drivers use them.

Changes since v3
- Added missing Kconfig depends on SHA256

Changes since v2
- Added missing Kconfig depends on MD5/SHA1

Changes since v1
- Moved arrays from headers to c file and made them EXPORT.

  crypto: hash: add zero length message hash for shax and md5
  crypto: niagara: Use precalculated hash from headers
  crypto: ccp: Use precalculated hash from headers
  crypto: ux500: Use precalculated hash from headers
