[edk2-devel] [Patch V2] BaseTools: Enable Module Scope Structure Pcd

Posted by Bob Feng 6 days ago
This patch is to enable the Module scoped Structure Pcd usage.
User can set structure pcd field value in module scope. For example,
under the [components] section of a dsc file, user can override some
field value for a specific module.

  Package/Module.inf{
