+# When DxeCore dispatching all DXE driver, this module will produce architecture protocol

+# interface of protocol gEfiBdsArchProtocolGuid, then BDS phase is entered.

+# Generally, this module take reposiblity to connect all necessary devices for platform boot,
+# these boot device path are hold in PlatformBdsLib library instance produced by platform.
+# For legacy boot, BDS will transfer control to legacy BIOS after legacy boot device is select.
