Well, in fact I have a beginning of something working here :
* I've added very basic support for Blackfin in Crosstool-NG.
Crosstool-NG is therefore able to generate a cross-compilation
toolchain for Blackfin (FDPIC ELF binary format). The support is
very, very basic and there are certainly some issues. This feature
is available in Crosstool-NG 1.7.0.
* I have made some very basic modification to Buildroot, and I'm able
to generate a root filesystem for Blackfin with just Busybox (I
haven't tried other packages at the moment). If you're interested in
this basic beginning, let me know and I'll clean it up. However, be
ready for some deep troubles : Blackfin support in CT-NG and
Buildroot is really in pre-alpha-horribly-untested-buggy-stage.
For now, it only works with Busybox compiled statically, but the
filesystem boots on a real Blackfin platform. For some reason, dynamic
libraries do not work (dynamically-linked programs simply exit, without
any error message and I didn't had the time to investigate).
