[U-Boot] [PATCH] driver: net: fsl-mc: remove MC firmware version check

[Stuart Yoder]

The MC version numbers provide no meaningful information
about binary interface compatibility, so remove the
check which refuses to start the MC unless a specific
version is found.

Version checking is supposed to be done at the individual
object level, and individual drivers are responsible
for their own version checking.

As per my understanding, version of individual components are fix in a major MC release.
Are you saying, there is possibility of object version change in a minor MC release?
