Subject: [PATCH] mvebu: image: fix generic-arm64.bootscript mmc selection
Not all versions of ESPRESSObin require SD card, but can
be booted from the internal emmc flash (mmc dev 1) instead.
Add a simple check in the bootscript to see which mmc device
is detected and boot from it using mmcdev variable.
