Hi Fabio,
(I'm sorry if I've missed some recipients or broke the email thread but
I got Fabio's email from the infradead archive.)

This results in a regression for those devices where U-Boot is supposed
to inject the partition sub-nodes. For example, this is the case for
cm-fx6 module based devices like the Utilite Pro.
Linux fails to parse the partitions and reports:
[ 9.330881] spi0.0: error parsing ofpart partition
/soc/aips-bus@2000000/spba-bus@2000000/ecspi@2008000/m25p80@0/partition@0
(/soc/aips-bus@2000000/spba-bus@2000000/ecspi@2008000/m25p80@0)
[ 9.330887] mtd: failed to find partitions; one or more parsers
reports errors (-22)
Also, the documentation does not forbid the #address-cells/size-cells if
no partitions are present.
So, please, drop this patch (or exclude at least the cm-fx6 related change).
Thanks!
Christopher
