Fastest Boot sequence for AM335x MPU

Which is the fastest boot sequence for booting the AM335x MPU?  Is it parallel NAND?  Parallel NOR?  SD?  SPI?  My customer wants to boot into VxWorks as fast as possible.  Any recomendations would be great.

    You can achieve fast boot with NAND, NOR and SD. With SPI flash it will be tough to achieve it. With NAND and SD you should be optimize the driver to be achieve high read throughput. Using NOR, and along with XIP(execute in place) to a certain extend you can achieve faster boot time.  

    If your customer is trying seriously to reduce the boot time, we can help as we've lot of expertise on boot time reduction. We've done boot time optimization on different TI platforms and has achieved very good boot time numbers as good as 2.6 secs on Linux with applications. We could boot linux kernel with bootloader and mount the filesystem in about 700ms on DM36x. If you are interested please get in touch with us.
