[edk2-devel] [PATCH 4/4] FmpDevicePkg/FmpDxe: Use FmpDependencyLib and FmpDependencyCheckLib
Xu, Wei6
wei6.xu at intel.com
Tue Apr 28 13:25:30 UTC 2020
REF: https://bugzilla.tianocore.org/show_bug.cgi?id=2696
Remove the orginal Fmp Capsule Dependency implement, and use new
FmpDependencyLib and FmpDependencyCheckLib APIs instead. A platform
can perform the dependency check in a platform specific manner by
implementing its own FmpDependencyCheckLib.
