Support a new platform in arch/ppc or in arch/powerpc ?

[CHAVENT Paul]

Good morning.

I would like to port a bsp (for the motorola MVME5500 sbc) to the current (2.6.22.6) kernel.

Should i implement it in arch/powerpc ?

If i should do it in arch/powerpc, can i copy some code i need in arch/ppc ? For example, with kernel 2.6.18.1 i used arch/ppc/syslib/todc_time and arch/ppc/syslib/pci_auto, but perhaps i don't need it anymore ?

Is there any recommandation for arch/powerpc implementation ?

Thank you.

Paul.
