Ok. By the way, the mbar is include as property in our OpenFrimware. Moreover, the G2CORE CPU has a new SPR 'MBAR' which is the MBAR ;-). It would maybe make sense to create a new file (arch/powerpc/sysdev/mpc52xx.c) which would contain chip specific code.

Like mpc52xx_get_mbar(), mpc52xx_get_ipbfreq(), etc...

I updated a bit the patches. I applied Dale requests.
My kernel still compiles and boots. ;-)

Should I post the new patches?

Sure.


Ok. Should be done this morning.


Here is is ;-).
As my mailer can insert a file, I copy paste. I hope it's still ok...
