I don't have any problems with mainline U-Boot and SPL on my DE0-NANO-BOARD:

U-Boot SPL 2016.03-00307-ge4fb863 (Mar 20 2016 - 10:37:13)
drivers/ddr/altera/sequencer.c: Preparing to start memory calibration
drivers/ddr/altera/sequencer.c: CALIBRATION PASSED
drivers/ddr/altera/sequencer.c: Calibration complete
Trying to boot from MMC

U-Boot 2016.03-00307-ge4fb863 (Mar 20 2016 - 10:37:13 -0500)

CPU: Altera SoCFPGA Platform
FPGA: Altera Cyclone V, SE/A4 or SX/C4, version 0x0
BOOT: SD/MMC Internal Transceiver (3.0V)
Watchdog enabled
I2C: ready
DRAM: 1 GiB
MMC: dwmmc0 at ff704000: 0
In: serial
Out: serial
Err: serial
Model: Terasic DE0-Nano(Atlas)
Net: eth0: ethernet at ff702000
Hit any key to stop autoboot: 0

Sorry, I know that doesn't help. So let's walk through my workflow. I am
not using any Altera tools when I build.

$make socfpga_de0_nano_soc_defconfig
$make u-boot-with-spl.sfp
$dd if=u-boot-with-spl.sfp of=/dev/sdb3

My gcc is: arm-linux-gnueabi-gcc (Ubuntu/Linaro 4.7.3-12ubuntu1) 4.7.3

Has the board ever worked for you at all? Can you try this image:
