From ef47683646516002694729986d19713e49b903e3 Mon Sep 17 00:00:00 2001 From: Hannes Schmelzer Date: Tue, 20 Sep 2016 18:10:43 +0200 Subject: cmd/fdt: add possibilty to have 'extrasize' on fdt resize Sometimes devicetree nodes and or properties are added out of the u-boot console, maybe through some script or manual interaction. The devicetree as loaded or embedded is quite small, so the devicetree has to be resized to take up those new nodes/properties. In original the devicetree was only extended by effective 4 * add_mem_rsv. With this commit we can add an argument to the "fdt resize" command, which takes the extrasize to be added.
