Have you seen this link[1]?
Yes, but that is by far not all of the registers used in the sequencer.c, is it ?
Looks like it's in the entire emi.pdf file[1]. Please look at volume 3, or page 531 of 895. The section for the UniPHY.
I extracted all the possible addresses used in the sequencer while cleaning it up, they're below. I cannot find these in any documentation. I checked the EMI RM, sure, but there seems to be many more registers all around the place than what are described in the EMI RM. Any ideas please ? Maybe this is not even the UniPHY anymore ?
Hi!
I'll try to get those questions answered for you shortly.
Thanks!
BTW, I tested out our your branch, but I think I'm missing a step as where to put the SPL DTB?

Do:
make u-boot-with-spl-dtb.sfp
Does your updated branch still work for you on the SoCKit? I'm hitting the dreaded "CALIBRATION FAILED" on all my boards here, the devkit, SoCKit and the new Atlas SoCKit.
