This review is just for reference if someone out there need to boot olimex am3352/am3359 SOM on a newer u-boot. I have no intention that this should be committed into the ports tree.
The Olimex provided u-boot can be found here:
https://github.com/OLIMEX/u-boot-2013.10-ti2013.12.01-am3352_som/
Device tree is here:
https://github.com/OLIMEX/OLINUXINO/tree/master/SOFTWARE/AM335x/patches
Some changes to the device tree are made to make it boot.
At least the AM3352 doesnt boot right away, after poweon you need to press the reset button to make it boot - I dont know why and I will not investigate it closer.
My personal use for this is to verify that the TI code in FreeBSD works with other hardware than the BeagleBone serie thats available for anyone.
