%define ob_desc \
The OpenBIOS project provides you with most free and open source Open Firmware \
implementations available. Here you find several implementations of \
IEEE 1275-1994 (Referred to as Open Firmware) compliant firmware. Among its \
features, Open Firmware provides an instruction set independent device \
interface. This can be used to boot the operating system from expansion cards \
without native initialization code. \
\
It is Open Firmware's goal to work on all common platforms, like x86, AMD64, \
PowerPC, ARM and Mips. With its flexible and modular design, Open Firmware \
targets servers, workstations and embedded systems, where a sane and unified \
firmware is a crucial design goal and reduces porting efforts noticably. \
\
Open Firmware is found on many servers and workstations and there are sever \
commercial implementations from SUN, Firmworks, CodeGen, Apple, IBM and others. \
\
In most cases, the Open Firmware implementations provided on this site rely on \
an additional low-level firmware for hardware initialization, such as coreboot \
or U-Boot. \

%description %ob_desc
# building firmwares are quite tricky, because they often has to be built on
# their native architecture (or in a cross-capable compiler, that we lack in
# koji), and deployed everywhere. Recent koji builders support a feature
# that allow us to build packages in a single architecture, and create noarch
# subpackages that will be deployed everywhere. Because the package can only
# be built in certain architectures, the main package has to use
# BuildArch: <nativearch>, or something like that.
# Note that using ExclusiveArch is _wrong_, because it will prevent the noarch
# packages from getting into the excluded repositories.
#
# Openbios is even trickier compared to other firmwares, because the same
# source must originate firmwares for multiple architectures. The magic here
# is to only create the subpackages in the architectures that can build it.
