OK, I can remove them from the TQM85*.dts files but I think the problem is more general. It seems to be frequently used for similar purposes, also in the code, at least in 2.6.26-rc4: $ cd linux-2.6/arch/powerpc/boot/dts $ grep -l 'cell-index' *.dts | wc -l 58 Wolfgang ^ permalink raw reply [flat|nested] 25+ messages in thread
