Subject: [patch] MdeModulePkg/VarCheckHii: Enhance VarCheckHiiLib to support bit check
Date: Fri, 27 Oct 2017 15:25:22 +0800 [thread overview]
Message-ID: <1509089122-135376-1-git-send-email-dandan.bi@intel.com> (raw)
VarCheckHiiLib check the value set to storage based on the possible value
listed in the vfr file. Since we have enhanced vfr to support Question
value stored in bit field, so now enhance VarCheckHiiLib to support bit
field check.
