EDKII_UFS_HC_PLATFORM_PROTOCOL will allow the platform to inject
platform specific logic into standard UFS flows. Right now we
support callbacks pre and post host controller enable and pre
and post link startup. We also allow the platform to override
host controller capabilities and version which might be usefull
to manage silicon bugs or allow testing experimental features
from new version of the specification.
