+ * mkbootimg --kernel /dev/null --ramdisk /dev/null --base 0x80000000 --kernel_offset 0x00008000 --ramdisk_offset 0x02000000 --second_offset 0x00f00000 --tags_offset 0x00000100 --pagesize 2048 --header_version 0 -o ramdisk.img"
+ *
+ * As this device has no boot partition, you'll have to create
+ * one yourself.
+ * To create the partition follow these steps:
+ * ./parted /dev/block/mmcblk0

+ * resizepart 55 31209799kB
+ * mkpart boot ext2 31209799kB 100%
