It seems I am not alone, there has been other reports of similar
issues and some combos work some dont
I have ported this patch

http://e2e.ti.com/support/processors/f/791/t/733651?PROCESSOR-SDK-AM335X-MLO-and-U-boot-issues-u-boot-spl-section-rodata-will-not-fit-in-region-sram-

and now my build problems are gone,

Added couple of other patches on top for beaglebone, and now I can
