[PATCH v1 0/3] fdt: Fix mtparts fixup

[Francesco Dolcini]

From: Francesco Dolcini <francesco.dolcini at toradex.com>

Recently we had a boot regression on colibri-imx7 because of a cleanup change
on Linux imx7.dtsi setting nand controller node #size-cells from 1 to 0.

Because of that Linux partition parser was no longer able to properly
parse the OF partitions leading to a boot failure, the above change was
reverted in the meantime as an immediate workaround, but some improvement
is required on both Linux and U-Boot.

This change improve the U-Boot part of it, #size-cell is set to 1 when
it has an invalid value. This has the limitation to work only with devices
smaller than 4GiB. In general the suggestion from the Linux MTD maintainer would
be to just deprecate using this U-Boot function and pass the MTD partitions
from the command line, unless they are statically defined in the DTS file
in the first place.

This series therefore convert colibri-imx6ull and colibri-imx7 to pass the
partition list from the command line instead of fixing up the DT.
