[U-Boot] [PATCH v2 3/6] colibri_vf: use device-tree for MTD partitions

Stefan Agner stefan at agner.ch
Wed Nov 30 22:41:54 CET 2016


From: Stefan Agner <stefan.agner at toradex.com>

Use device-tree fixup to communicate the MTD partitions to the
kernel. U-Boot's mtdparts environment variable will be used as
partition source for the device-tree based partition table too.
