updated to UPA1AM18, emmc boot no longer available

I had a functional copy of arch Linux fully updated and running with whatever bios shipped with the board. As I was updating, I noticed a warning stating that the file was longer than the flash area being written to and that some of the file would not be written. I can still access EFI shell and setup interface, but the option to boot into my OS on emmc is no longer available. Thoughts?
