Change the prompt to instruct the end user to wait for the installer
instead of just "Press TAB for boot options". Hopefully more intuitive
now.
Rebrand to LE in the code also. :)
needs double space on storage partition for extracted .img file
KERNEL/SYSTEM files are copied directly from mounted partition to /flash
tested on imx6 project
size of initramfs/kernel increased by ~40kB
if downgrade with image without included .md5 files
user needs to create file .nocheck (there is no integrity
checks done in this case - can be unsafe)

Mtools is used to format and copy files to vfat partition.
Populatefs is used to copy files to ext4 partition.
Tested on imx6 with u-boot, Generic with BIOS and EFI boot.
To avoid messing around with ext4 partition we could also provide "empty" disk image file. Both partitions would be already formatted and storage partition would already contain resize file. Then mkimage script would only copy kernel, system, bootloader files and install bootloader.
But current approach is more flexible for future use.
Allow configuring extra kernel command line arguments by using the
EXTRA_CMDLINE variable. The patch handles EXTRA_CMDLINE only for the
bcm2835 boot loaders.
