回复: [edk2-devel] [PATCH - resend] MdeModulePkg/BootLogoLib: Center logo 38.2% from top of screen

["gaoliming" <gaoliming@byosoft.com.cn>]

Patrick:
  I am OK for this extension to meet with Microsoft recommendation. This
change is a new feature. Can you submit one BZ
(https://bugzilla.tianocore.org/) for it?  

Thanks
Liming
