Issac is removed.
Hi Lisa,
These two packages are diverging in IPMI transport (GenricIpmi) and some other
high level drivers such as IpmiCommandLib. I plan to take below actions.
1. Remove IpmiCommandLib from IpmiFeaturePkg, as the IPMI command support in
ManageabilityPkg has the same functionalities with few newly added IPMI
commands. This library is independent of IPMI transport interface.
2. Remove Frb, IpmiFru, OsWdt and SolStatus from IpmiFeaturePkg as those were
migrated to ManageabilityPkg already.
3. I will get back to GenericIpmi and turn it into ManageabilityPkg framework
then remove GenericIpmi from IpmiFeaturePkg.
So I would like to take back my suggestion having you to send the patch against
ManageabilityPkg. As the transport implementation has some gap between these
two packages.
Thank you
Abner
