[U-Boot-Users] [PATCH] Calculate PLPRCR fields for MPC86x boards

[U-Boot-Users] [PATCH] Calculate PLPRCR fields for MPC86x boards

[Pantelis Antoniou]

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.

Best regards,

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
