Re: [PATCH 01/15] .pytool/Plugin: Add a plugin LicenseCheck

["Zhang, Shenglei" <shenglei.zhang@intel.com>]

Five sorts of license are accepted in edk2(described in readme). They are BSD (2-clause), BSD (3-clause), MIT, Python-2.0 and zlib.
Minus non bsd plus patent license, they are BSD (2-clause) and BSD (3-clause).

Thanks,
Shenglei
