I understand that with the progress we make on EFI implementation and 
other parts of U-Boot the U-Boot image size is growing too big for 
direct loading by the primary boot loader.

The OPENRD boards have abundant memory, e.g. openrd_ultimate_defconfig 
refers to a board with 512 MB RAM.

So I think completely disabling EFI is not the solution.
Instead building an SPL should be enabled for this architecture when the 
image is becoming too big for direct load.

I am copying in the KIRKWOOD maintainers go get their view.

Best regards
