Subject: lantiq: enable retrieving kernel args from bootloader
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=a9968d9cb8cb10030491fa05e24b00bd42f6d3a9;p=openwrt%2Fstaging%2Fdangole.git

lantiq: enable retrieving kernel args from bootloader

This patch is a device tree enhancement that IMHO is worthy of mainline.
It allows the bootloader's commandline to be preserved even when the
device tree specifies one.
