Here is what I am seeing with core-image-minimal
32612024 bytes read in 11244 ms (2.8 MiB/s)
18179 bytes read in 30 ms (590.8 KiB/s)
## Booting kernel from Legacy Image at 00100000 ...
Image Name: Linux-3.12.0
Image Type: ARM Linux Kernel Image (uncompressed)
Data Size: 32611960 Bytes = 31.1 MiB
Load Address: 00008000
Entry Point: 00008000
## Flattened Device Tree blob at 00000100
Booting using the fdt blob at 0x00000100

OK
Loading Device Tree to 03ff8000, end 03fff702 ... OK
Starting kernel ...
If I make the uBoot image ~3 MB just using core-image-minimal-initramfs, I get
different results. Here are the relevant part of my uboot configuration:
fdtaddr=0x00000100
fdtimage=/boot/socfpga_mitysom5csx.dtb
fdtimagesize=0x2000
mmcboot=setenv bootargs console=ttyS0,115200 root=${mmcroot} rw rootwait;bootm
${loadaddr} - ${fdtaddr}
mmcload=mmc rescan;${mmcloadcmd} mmc 0:${mmcloadpart} ${loadaddr}
${bootimage};${mmcloadcmd} mmc 0:${mmcloadpart} ${fdtaddr} ${fdtimage}
mmcloadcmd=ext2load
mmcloadpart=2
mmcroot=/dev/mmcblk0p2

core-image-minimal should boot you into shell console. That should have been
enough

make sure that memory is not overlapping and is initiaized
