Working frv toolchain?

[Jan Dittmer <jdi@l4x.org>]

With gcc 4.0.0 and binutils 2.15.94 I get:

   CC      arch/frv/mm/dma-alloc.o
arch/frv/mm/dma-alloc.c: In function 'consistent_alloc':
arch/frv/mm/dma-alloc.c:66: error: impossible constraint in 'asm'
make[2]: *** [arch/frv/mm/dma-alloc.o] Error 1
make[1]: *** [arch/frv/mm] Error 2
make: *** [sub-make] Error 2

http://l4x.org/k/?d=35919 for details

What is a known working toolchain for fr-v? Is there a
mailing list for frv related problems?

Thanks,

Jan
