does s3c6400 have different clock controller compared to s3c6410?
I have only old manual of s3c6400 and it has the same equation for pll
clock setting.
Please take a look into arch/arm/cpu/arm1176/s3c64xx/speed.c. There
are common functions for both CPU's and
they work ok. So i guess my patch should not break s3c6400 operation.
Btw, we don't have any working s3c6400 board in main line and it seems
nobody is interested to have one.

Darius.
