Hi Albrecht, I don't recall who proposed this patch, but exactly this solution is around for a longer time (mayby you search archives...). On my board, I have a flash chip attached to the LocalBus in 16-bit mode. Based on 3.2.16, the patch is: Thanks for your answer and yes, this patch

Here are a few powerpc fixes. Arguably some of this should have come to you earlier but I'm only just catching up after my medical leave. Mostly these fixes regressions, a couple are long standing bugs. Benh, This should probably go up now too: http://patchwork.ozlabs.org/patch/167270/
