Given that the licensing for carl9170fw is a bit special[1] for a
firmware image targetted at a different architecture and not easy to
fulfill in a way that avoids wget on the buildds or code duplication,
I've started some preliminary packaging for it at:
Vcs-Svn: svn://svn.berlios.de/fullstory/firmware-carl9170/trunk
Vcs-Browser: http://svn.berlios.de/svnroot/repos/fullstory/firmware-carl9170/trunk/
While this should meet upstream license conditions in wording and
spirit and may pass ftp-master checking, its strong dependencies
on packaging structures of binutils-source, newlib-source and the
versioned gcc-$(GCC_VER)-source make it rather fragile and high
maintenance, not to say downright ugly (looking at the list of
build-depends). This packaging compiles the sh-2 cross-compiling
environment at build-time, as introducing a newlib based sh-2
cross-compiling toolchain for this single package is hardly a preferred
option for Debian and binutils/ newlib/ gcc maintainers.
Please regard this as an initial attempt to solve this issue and feel
free to re-use this or parts of it at your convenience. While I'd
volunteer to co-maintain this (or derivatives of this packaging), it
still needs an active Debian uploader due to its rather high
maintenance requirements (adaptions to future {binutils,newlib}-source
versions or bumping the versioned build-requirements whenever old
gcc-$(GCC_VER)-source versions get removed from the archive).
Warning, system requirements for building this package are quite high:
- ~140 MB build-dependencies
- ~3.4 GB temporary build space
- a good half hour compilation time (mostly spent on the toolchain) on
fast computers, allowing parallel building through DEBBUILDOPTS helps
significantly.
+ build-tested on amd64 and kfreebsd-amd64, providing bit-identical
results
+ functionality confirmed with 0cf3:9170 Atheros Communications, Inc.
AR9170 802.11n on kernel 3.0.1.
