I'm actually running the SC584 ez-kit and running through the instructions to load u-boot, finding that the instructions were referencing the hpc and were not applicable to me and changing this to the lpc command lines (instructions could probably do with an update for this), I still cannot get u-boot to run.
It's loading but this is as far as it gets:
"U-Boot 2015.01 ADI-1.1.0 (May 30 2016 - 14:25:38), Build: jenkins-IP119-UBOOT-STAGE-DEB-label=make_deb_package-248
CPU: ADSP ADSP-SC584-0.0 (Detected Rev: 1.1) (spi flash boot)"
U-boot then appears to freeze up?
