Hi Chris,

I have a custom board that sees correctable ECC errors (when running

see the errors.
I've also had a tame hardware engineer (if there is such a thing)
looking at the timing waveforms comparing the stock u-boot behaviour
against Marvell's bootloader.
The changes for this series have been derived by comparing scope
captures and register output between the same system running stock
u-boot and Marvell's USP.
Changes in v2:
- Update tODT_OFF_WR as well
- Added patches 2-4
Chris Packham (4):
ddr: marvell: only assert M_ODT[0] on write for a single CS
ddr: marvell: use correct TREFI value
ddr: marvell: update additional ODT setting
ddr: marvell: update ddr controller init and freq

Big thanks for working on this. All patches:
Applied to u-boot-marvell/master.
Thanks,
