Sorry for the delayed response - got called away, but am back to this now. I patched socfpga_common.h and re-built the project. I picked up spl/u-boot-spl-dtb.sfp and u-boot-dtb.img and transferred them to the SD card with:
dd if=u-boot-spl-dtb.sfp of=/dev/sdf3 bs=64k seek=0 dd if=u-boot-dtb.img of=/dev/sdf3 bs=64k seek=4
Tried this with both the original DT set (socfpga.dtsi, socfpga_cyclone.dtsi, socfpga_cyclone5_sockit.dts) that came with the u-boot v2016.01 download and also an Altera-patched DT set that I've used to boot into Linux numerous times.
When I start up the board I get:

I'm not a Quartus user, so I haven't done anything with the qts-filter.sh script you mentioned. Do I need to? I don't have any custom FPGA logic - it's just the Terasic board out of the box.
Thanks for any help!
Even without the custom FPGA logic the files generated from qts-filter.sh need to match your board. Sets up PLL and SDRAM parameters. I'm not familiar with the Terasic dev board ( I do have the altera devkit, but haven't used it for awhile). I'd hope the files in the git repo are correct for your board. Without the corresponding qsys project it's hard to be sure.
Hi Phil,
So as my next attempt, there was a Quartus/Qsys example that came with the Terasic board (specific to my Rev. of the board).
* I took the contents of the 'handoff folder', .sof, and .sopcinfo file. * launched an "Embedded Command Shell" from EDS 15.0 and then the BSP editor GUI * pointed the BSP editor to the "handoff folder", and hit "Generate" to produce iocsr, pinmux, pll, etc. files * applied qts-filter.sh to these files, the output of which I then dropped into the u-boot source @ ../board/terasic/sockit/qts * rebuilt uboot spl & image, but got a similar result:
U-Boot SPL 2016.01 (Mar 02 2016 - 22:13:31) drivers/ddr/altera/sequencer.c: Preparing to start memory calibration drivers/ddr/altera/sequencer.c: CALIBRATION FAILED drivers/ddr/altera/sequencer.c: Calibration complete SDRAM calibration failed. ### ERROR ### Please RESET the board ###
Except now it repeats four times, whereas before it only printed out once.
It that essentially the correct procedure? Is it now a matter of looking through the include files that where generated by qts-filter.sh to find a setting that is "off"?
(BTW - my first attempt was to use EDS 13.0, but that resulted in several undefined macros when it came time to compile u-boot with the qts-filter-generated code. How does one know which tool version to use?)
Thanks, --George
The sd card write commands look correct. I just used a dts files in the uboot source but modified a couple of things. Update Mem size and serial port speeds to match our requirements.
I also modified a few debug statements so the spl outputs a bit more info by default. Output is alot closer to the altera supplied uboot tree.
My spl bootup is:

Marek who committed the terasic config may be able to help. It most likely a mismatch in the qts config vs hardware.
