[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index] [PATCH 3/5] xen/ppc: Add OPAL API definition header file
OPAL (OpenPower Abstraction Layer) is the interface exposed by firmware
on PowerNV (bare metal) systems. Import Linux's header definining the
API and related information.
