[U-Boot] [PATCH] pepper: Add support for DDR3 variants

[Ash Charles]

Hi Tom,

There is actually an EEPROM on new boards that we'd like to use in the
future in order to detect that we should use DDR3 (and frankly,
everything will be DDR3 going forward).  We still don't have
everything sorted in hardware and at the factories for programming the
eeprom though.  This patch was a shot at capturing and makes generally
available the interim measure that has been carried for a bit on our
Gumstix tree.  If this is not appropriate for mainline, we can
certainly carry it until hardware gets settled.
