From: Jagadeesh Krishnanjanappa <workjagade...@gmail.com>
The cryptographic unit is optional for the Cortex-A72, but it was
included by default previously. This breaks building systems that
lack this functionality when using tune-cortexa72.inc.
To correct this, add a crypto entry in the tune file. Since CRC is
optional for ARMv8.0, do the same thing while we're at it.
For platforms that had been happily using tune-cortexa72.inc, a slight
degradation of performance will occur using the default. To correct
this, simply add:
DEFAULTTUNE = "cortexa72-crc-crypto"
