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)

12 years agospi: fix mxc_spi_slave structure allocation to clear memory
Matt Sealey [Fri, 17 Aug 2012 08:15:10 +0000 (08:15 +0000)]
spi: fix mxc_spi_slave structure allocation to clear memory

Use calloc() instead of malloc() to allocate the mxc_spi_slave structure.
Clearing the memory is necessary since most of the time this gets done
super early in boot, but on warm reboots, and when SPI probing is done
long after the init stages it could actually pick up previously used memory,
and things like the chipselect polarity and other data end up being filled
with trash data if not explicitly set by the board files.

This solves a semi-random, almost unreproducable error whereby SPI devices
act very, very strangly on boot. Tested on Efika MX over several years..
