The DDR validation tool (which is part of Processor Expert) allows to evaluate leveling parameters for CR105/CR106/CR110. Several runs have been made with Colibri VF50 and VF61 and it seems to evaluate very similar values. Use this values by default. Note: The newly evaluated parameters seem to require CTLUPD_AREF to be enabled! Note 2: The tool also evaluated 6 as a new value for PHY02/18 GATE_CFG (Coarse adjust of gate open time). However, this seems not to work in practise. Signed-off-by: Stefan Agner <stefan.agner@toradex.com> Acked-by: Marcel Ziswiler <marcel.ziswiler@toradex.com>
