where to modify my system clock in a tqm8xxl model?
hello,all
Congratulations on the release of the u-boot-1.0.0!Can you tell me
where to set the system clock in a tqm8xxl model? My hyperteminal has displayed this (there are some "printf" added):
U-Boot 0.4.8 (Oct 31 2003 - 15:47:15)
gd->cpu_clk=25000000
immr=0xff002101
pvr=0x500000
CPU: XPC823xxZTnnB2 at 25 MHz: 2 kB I-Cache 1 kB D-Cache Board: WindRiver mdppro8xx DRAM: 16 MB
before relocate_code()
Now I want to set my system clock to 50MHz,but I don't know how to
modify,which file should I modify?I know the gd->cpu_clk is initialized in cpu/mpc8xx/speed.c.
Thank you for your time!

^^^^^^^^^^^^^^^^^^^^^^^^^^^^
This does not look like a TQM8xxL module at all.

All these setting are done in the board config file (include/configs/<board>.h)
