From cdb3053a3af5e71ee070d9a645f52f80c2eae5c6 Mon Sep 17 00:00:00 2001 From: Adrian Panella Date: Thu, 23 Jun 2016 18:56:47 +0200 Subject: ipq806x: activate ATAG DTB mangle and EA8500 rootblock in dts The command-line arguments provided by the boot loader will be appended to a new device tree property: bootloader-args. If there is a property "append-rootblock" in DT under /chosen and a root= option in bootloaders command line it will be parsed and added to DT bootargs with the form: XX. Only command line ATAG will be processed, the rest of the ATAGs sent by bootloader will be ignored. This is usefull in dual boot systems, to get the current root partition without afecting the rest of the system.
