Hello Adam,

By removing EXT support from SPL, it makes room for the extra overhead of enabling OF_CONTROL in SPL. With SPL_OF_CONTROL enabled, extra options need to be added to the device tree to tell it which portions of the tree are needed early in boot time
Unfortunately, with these options as-is, the system doesn't boot nor does it display anything on the UART. I don't have a debugger readily available, but I have seen others with AM33x boards which are similar to OMAP3 boards. This is posted as an RFC just in case anyone has any suggestions on what might be missing.
On an AM335x board I had problems when moving from embedded to separate DTB. Even if deprecated you should probably give CONFIG_OF_EMBED a try. If this works you could go back to CONFIG_OF_SEPARATE and probably give CONFIG_SPL_SEPARATE_BSS a try. Also CONFIG_DEBUG_UART (assumed the pin configuration is working) did help me quite a lot.
