To this I asked my linux group in Freiburg and got following answer in German from Tomas (tuxteam.de): -------------------------------------------------------------------------- Die Antwort darauf ist komplizierter, als es einem lieb sein kann :-) "Blob" hat da nämlich unterschiedliche Bedeutungen (vermutlich lässt sich die Liste verlängern): (1) zum einen, nicht-freie Treiber, die direkt im Adressraum des Linux kernels ausgeführt werden (strenggenommen verletzen sie die GPL, aber die Linux-community ist da... "tolerant" [1] (2) dann ist die eng verwandte "Cousine", die im Kernel zwar einen freien "Treiber" hat, der aber nur eine Hülle ist, die die eigentliche Arbeit an ein Programm in user space delegiert, das proprietär ist (3) schliesslich ist es so, dass der Broadcom BCM28xx (oder BCM27xx) [2] nicht "nur eine ARM CPU" ist, sondern ganz viele verschiedene Subsysteme umfasst (im Jargon ist das ein SoC, ein "System on a Chip"). Jedes dieser Subsysteme hat vielleicht einen, vielleicht mehrere Prozessoren, am prominentesten beim Raspi ist wohl der Grafik-Coprozessor (VideoCore IV), der auch zum Booten des ganzen Systems zuständig ist. Auch die wollen Code, der auch als Blobs in Erscheinung treten kann, die der Linux-Kernel einfach nur durchreicht. Also: ohne (3) gibt es beim Raspi nicht mal Booten ;-) Meines Wissens ist Raspi in (1) und (2) weitgehend "sauber" (Korrekturen erwünscht!), (3) ist allerdings weitaus schwieriger (es gibt m.W. aber auch Leute, die an dessen reverse engineering dran sind).

"tolerant") [1] (2) then, there is a nearly related "cousin" who admittedly has a free "driver" but this one is only a cover which delegates the real work to a propriatary program in user space (3) eventually it is so that Broadcom BCM28xx (or BCM27xx) [2] isn't "only an ARM CPU" but contains a bunch of many different subsystems (in jargon a SoC, a "system on a Chip"). Everyone of these subsystems has possibly one, possibly several processors. Presumably the most prominent with the Raspi is the grafic-coprocessor (Videocore IV) which is responsible for booting the whole system too. Also these have code which might become evident as blobs which the linux kernel simply hands through. Consequently: without (3) Raspi wount boot ;-) As far as I know (Tomas, tuxteam.de) with concern to (1) and (2) Raspi to a large extend is "clean" (corrections are welcome!), though (3) is much more difficult (there are, as I think, people who are working on reverse engineering of it). Broadcom, after hesitating initially, seems to be friendly against those efforts. This all is with a bit of error margin, because I didn't look into it for a rather long time. Completions are welcome (then I would learn something too ;-) lg (liebe Grüße) [1] A topic for itself with possibilities to controversies as one can imagine.
