efikamx: sync Smartbook DDR settings in DCD with those found in Genesi's production U-Boot
We have no idea where the DCD was derived from for Smartbook support, but they differ from the Smarttop settings, MX51EVK settings and certainly don't correspond to any shipped or development version of U-Boot that Genesi has ever had on any Smartbook. So, copy the calibrated, verified settings from the U-Boot as shipped with every Smartbook since retail production. Remove those few settings that just set the POR defaults which have already been confirmed for the previous Smarttop DCD change. One of the lines is specific to i.MX51 TO3 designs and therefore TO2 Smartbooks will possibly not work so reliably with this new DCD; that said, TO2 Smartbooks basically don't exist at retail and the number of units in the world is less than 5 (3 of which are at the Genesi office or owned by Genesi employees). Many hours of memory testing confirms the new settings are stable. Patch v2: * picked the correct commit from our development tree, correcting tuned DDR ODF setting (which was correct anyway) Signed-off-by: Matt Sealey <matt@genesi-usa.com> Cc: Stefano Babic <sbabic@denx.de> Cc: Marek Vasut <marex@denx.de>
