The following patch (against latest 2.6 tree) adds support for the TQ
Systems TQM834x Boards. Verified on TQM8349L.

Note: for TQM834x board support actually to  compile  and  work,  two
previously submitted patches are required. See postings:

Sat, 22 Oct 2005   [PATCH 2.6] Add generic support for DS1377 RTC
Sat, 22 Oct 2005   [PATCH] Cleanup mpc83xx_restart() code
