From: Francesco Dolcini francesco.dolcini@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 not edit the DT partitions from U-Boot unless some dynamic tweaking is required.
This series therefore convert colibri-imx6ull and colibri-imx7 to pass the partition list from the command line instead of fixing up the DT.
