Unfortunately, my crazy idea to follow/honor industry standard drive booting/partitioning in the iMX bootrom fell on deaf ears. At least they skipped over the MBR.
Indeed, I must have submitted this change request to various places about 10 times since MX51.
It really impedes low-cost design of things like ChromeBooks (which need EFI partitions) without adding in some kind of internal boot ROM to get the system running. If you can save even $1.50 for SPI NOR on every board by simply making the offset 32KiB, and not having to solder fixed-size NAND to the board for motherboard production, it's worth it. Maybe for MX7 *fingers crossed*.
Problem is this is a vicious circle - if nobody makes a system that requires EFI partitions they won't think it's worth it, and if the SoC can't support EFI partitions, nobody will make them.
