Re: [Patch 00/12] CryptoPkg: Remove EC PCD and merge perf opt OpensslLibs

["Yao, Jiewen" <jiewen.yao@intel.com>]

OK. That means we need manual write a wrapper for all EC APIs in Openssl Lib for internal usage.
More precisely, a wrapper for the delta between OpensslLib and OpensslLibFull, right?

There will be size difference between those two solutions, because the code other than EC will be include in the function.

Why not use NO_EC macro from openssl directly?

Thank you
Yao Jiewen
