Not sure who else can/should use it. An updated version of this work is here:=20 http://people.freebsd.org/~mlaier/firmware-20060125.tgz It includes the following changes: =2D Firmware module generation with awk and ld (no special tool required). = The=20 kmod.mk Makefile has been changed to support this and it's now very easy to= =20 build a firmware module. =2D Versioning =2D firmware_put() safe from any context =2D digi(4) converted. ATTENTION: this was done blindly - if you have digi= (4)=20 hardware I'd appreciate reports! =2D Plenty iwi(4) changes which make it work much better for me - though th= ere=20 are some rough edges still. =2D firmware(9) manpage To try it, just copy the contents of the tarball over src and apply the two= =20 patches in sys/conf to the respective files. The firmware support can be=20 loaded as a module itself, so testing is really easy. My plan is to import the basic firmware support on the weekend (if no=20 objections are raised). Drivers would be converted later after some more=20 testing. The aim of this is to avoid more and more handrolled sollutions. = I=20 didn't yet have time to look at ispfw, but will do that as well. So, any objections? Comments? Feedback?
