2017-12-29ARM: imx6: Disable DDR DRAM calibration DHCOM i.MX6 PDKMarek Vasut
The DDR DRAM calibration doesn't work on T-topology sometimes, so disable it. Signed-off-by: Marek Vasut <marex@denx.de> Cc: Stefano Babic <sbabic@denx.de>
2017-11-16ARM: imx6: Adjust DDR DRAM settings on DHCOM i.MX6 PDKMarek Vasut
The board uses T-topology for the four x16 DRAM chips, so remove the write-leveling from the SPL as that is only usefly on fly-by topology and can be harmful on T-topology. Also update the DRAM timing with values from calibration on multiple boards. Signed-off-by: Marek Vasut <marex@denx.de> Cc: Stefano Babic <sbabic@denx.de>
