[OpenWrt-Devel] [PATCH 4/7] uboot-zynq: use a file to modify the default environment

Luis Araneda luaraneda at gmail.com
Mon Sep 3 21:39:59 EDT 2018


Follow the strategy of other targets and create a
default environment file, uEnv.txt, to configure the
behavior of U-Boot.
For now, use it to pass bootargs to the kernel
