Hi Simon, Geert Cc Mark
could you test this series as Geert does not have access to a bockw board? On Tue, Feb 11, 2014 at 09:56:47AM +0100, Geert Uytterhoeven wrote:quoted

I tested this patch, and it works well.
But there are some notes
1) m25p80 driver DT support seems strange ??
${LINUX}/Documentation/devicetree/bindings/mtd/m25p80.txt
has explain about DT of m25p80 driver, but,
${LINUX}/drivers/mtd/devices/m25p80.c
doesn't have driver :: of_match_table.
but, it is using of_property_read_bool() on probe.
Is it out-of-tree support ?? I'm not sure,
anyway, m25p80 driver didn't probe.
So, I quick-hacked this issue in my local environment.
2) it needs Geert's this patch

Kernel will hung-up without this patch
