Subject: [edk2-devel] [PATCH v5 1/1] MdeModulePkg: Add
BootDiscoveryPolicyUiLib.

This library extends Boot Maintenance Menu and allows to select Boot
Discovery Policy. When choice is made BootDiscoveryPolicy variable is set.
Platform code can use this variable to decide which class of device shall be
connected.
