Calculate PLPRCR fields for MPC86x boards
PATCH 1/1 Calculate PLPRCR fields for MPC86x boards
Hi.
The following patch adds a program in the tools directory which aids in the programming of the PLPRCR register for MPC86x based boards.
That is given an input clock xin and a target clock gclk2 it will output (if possible) the values of the PCPRCR fields required.
Regards
Pantelis

Thanks, added. (But target disabled by default in the tools/Makefile).
Will show up on CVS soon.

As a side note, we just found out that the 859/866 family ONLY supports up to 66MHz external bus... hopefully nobody else has been bitten by this.
if your core freq is >66MHz, you MUST use the external bus x2 divisor
