[edk2-devel] [edk2-staging][PATCH v2 2/2] edk2-staging/EmulatorPkg: Introduce Hii2RedfishBiosDxe driver
Nickle Wang
nickle.wang at hpe.com
Mon Jul 25 01:35:40 UTC 2022
Add Hii2RedfishBiosDxe driver with configure language defined in UNI
file in order to demonstrate the use of Redfish Platform Config
Protocol. Feature drivers under RedfishClientPkg will work with this
driver and provide the REST data to Redfish service.
