From: Alexander Feilke <alexander.feilke at ew.tq-group.com>

Integrates a new tq_eeprom sysinfo driver that reads & prints board
information during boot.

This is the basis for additional patches that will be sent along with
updates of the TQMa6 in the near future, including support for multiple
indexed sysinfo devices and VARD (variant detection) data for newer TQ SOM's.
