Honored ContributorHere are the clock manager registers from runs of both SPL1 and SPL2.
Maybe there is a script to display them (much) better, but for now it's easy to see that there are a few differences. Am not sure which might be relevant.... I will also note that U-Boot's mtest does not work in either SPL when testing SDRAM addresses, though it does when testing OCRAM.
