[U-Boot] [PATCH v2 0/4] ddr: marvell: update DDR driver

[Chris Packham <judge.packham@gmail.com>]

I have a custom board that sees correctable ECC errors (when running
memtester[1] from Linux). When I used Marvell's bootloader I didn't
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
