Salut,
le module devenant de plus en plus gros a cause du nouveau firmware de
l'eagle III et comme j'avais envi de faire mumuse avec l'interface
noyeau de chargement de firmware, j'ai codé un petit truc pour sortir le
firmware du module.
La taille du module est passe de 120 Ko a 80 Ko.
Ca devrait marche aussi bien sur les archi big et little indian.
Mon code (notament mk_fw) n'est pas tres propre (pas de gestion de
toutes les erreurs), mais si les mainteneurs du module sont interresser,
je pourrais le nettoyer.
Il pourrait peut etre aussi interressant d'utiliser la meme interface
pour le dsp, quoique il y aura toujours les options a passer au modem
et je sais pas si on peut differencier pots de idsn via les id du modem...
mk_kw.c est a placer dans driver/firmware et sert a generer les fichiers
eagle{I,II,III}.fw qui contiennent les image des firmwares.
Il peuvent soit etre charger a la main dans
/sys/class/firmware/xxx/data, soit via l'intermediaire de hotplug (cf
linux/Documentation/firmware_class/README ou la doc hotplug)
