This serial of patches have been submitted on 11, Aug., 2006. I wait for more than two months. there is no feedback, positive or negative.
I updated the patches based on the current u-boot git tree. I hope I will not wait for so long time again. Any feedback is welcomed. I'd like to refine the code according to your warm comments.
This series of patches add mpc7448hpc2 board support. Mpc7448hpc2 (taiga) board is a high-performance PowerPC server reference design,which is optimized for high speed throughput between the processor and the memory, disk drive and Ethernet port subsystems.
The board is designed to the micro-ATX chassis, allowing it to be used in 1U or 2U rack-mount chassis
