It seems to boot OK for me. See details and download link below:

md5sum board/intel/minnowmax/*.bin

md5sum b/minnowmax/u-boot.rom

Download u-boot.rom from:

https://drive.google.com/file/d/0B7WYZbZ9zd-3eDFaNHpFN2JrcUE/view?usp=sharing

(I use em100pro to download the image)
sudo em100 -s -p LOW -d b/minnowmax/u-boot.rom -c W25Q64DW -r
