sysutils u-boot-osd-customboard patchset
This port is a starting point for embedded custom boards based on OSD3358/AM335x with blank EEPROM. You have to adjust the device tree for your unique hardware.

I'm not sure that adding code from a vendor u-boot as patches is a good idea.
This will likely be a problem when upgrading to newer u-boot and that is not something that I want to deal with.

Of course it will be some work when upgrading u-boot.
Perhaps a more approachable path is to suggest upstream uboot to introduce a blank eeprom option for am335x.
