Unfortunately no.

BTW, U-boot is GPL v2.0+, would it be possible to cross port from U-boot?

For the worst case I can craft a new interface from scratch, as GRUB 
doesn't seem to need any write operation for the fs, thus quite some 
code can be truncated and all transaction related functionality can be 
removed.
