fixed and pushed onto mpc83xx master. regenerated patch below. thanks for the clarification David. Kim mpc83xx: don't set SICRH_TSOBI1 to RMII/RTBI operation In GMII mode (which operates at 3.3V) both SICRH TSEC1/2 output buffer impedance bits should be clear, i.e., SICRH[TSIOB1] = 0 and SICRH[TSIOB2] = 0. SICRH[TSIOB1] was erroneously being set high. U-Boot always operated this PHY interface in GMII mode. It is assumed this was missed in the clean up by the original board porters, and copied along to the TQM and sbc boards.
