The attached patch fixes the QSPI clock calculation on AM4372. The fixed prescaler of 4 in the PRCM unit was missing. That results in QSPI frequencies being too low.
Added Tom Rini on cc: because he is the TI ARM maintainer. There is no base commit because the patch stems from an older patched U-Boot version being used here. But it should apply cleanly to the current mainline U-Boot tree. PS.: I'm not on the list. Any questions should sent to me directly.
