%description
This package provides a daemon to load and run the OpenPower firmware's
Processor Recovery Diagnostics binary. This is responsible for run time
maintenance of OpenPower Systems hardware.


%package -n opal-utils
Summary: OPAL firmware utilities
Group: Applications/System

%description -n opal-utils
This package contains utility programs.

The 'gard' utility, can read, parse and clear hardware gard partitions
on OpenPower platforms. The 'getscom' and 'putscom' utilities provide
an interface to query or modify the registers of the different chipsets
of an OpenPower system. 'pflash' is a tool to access the flash modules
on such systems and update the OpenPower firmware.

%package -n opal-firmware
Summary: OPAL firmware
BuildArch: noarch

%description -n opal-firmware
OPAL firmware, aka skiboot, loads the bootloader and provides runtime
services to the OS (Linux) on IBM Power and OpenPower systems.
