Advantages of supporting OMAPBOOT:

  • Easy to use and extend for newer silicon versions and/or revisions.
  • Does not use a GPL license. Slim, efficient, lightweight and fast, focuses on doing the bare minimum needed to boot.
    • U-boot first stage = 33K and second stage = 233K, when built for OMAP5.
    • Omapboot first stage = 26K and second stage = 29K, when built for OMAP5. With recent speed optimizations, measured boot time from bootloader to kernel ~210ms for omapboot.
