[OpenWrt-Devel] [PATCH 2/2] mvebu: add squashfs image type to MMCProfile

Thu Apr 28 10:01:19 EDT 2016
From: Josua Mayer <privacy at not.given>
Added gen_mvebu_sdcard_img.sh to create bootable sdcard images. It takes
the bootloader and partition images to create a bootable sdcard image.
Partition Layout:
p1: fat32: for kernel, dtb and boot config files if any
p2: squashfs: for openwrt
This change is developed for the Clearfog, but should work on all A38x
SoCs that can boot from mmc.
