From 373054232eb5b0dcb3b76c3f6090b08160f10fac Mon Sep 17 00:00:00 2001 From: Pau Cabre Date: Mon, 3 Jul 2017 16:44:49 +0200 Subject: util,arch-arm: Added python script to generate ARM FS binaries This python script builds the bootloaders, kernels and DTBs for the VExpress_GEM5_V1 (aarch32/aarch64), VExpress_EMM and VExpress_EMM64 platforms (it checkouts some linux kernel repositories when needed).
