The new direction is to have everything under arch/powerpc, both 32 and 64 bit. The reason arch/ppc still exists is because some 32 bit platforms have not been fully migrated to the requirements to be merged into arch/powerpc. Namely, the code has to boot from an OpenFirmware like flattened device tree. The PPC 4xx family of processors, as an example, does not do this yet though there is work going on to adapt it. Eventually, arch/ppc will go away and all of PowerPC will be under arch/powerpc. That's the goal anyway. josh --------------------------------- Stay in the know. Pulse on the new Yahoo.com.

Yes, you're wrong. Some 32 bit boards are also under arch/powerpc now.

They did originally.

The new direction is to have everything under arch/powerpc, both 32 and
64 bit. The reason arch/ppc still exists is because some 32 bit
platforms have not been fully migrated to the requirements to be merged
into arch/powerpc. Namely, the code has to boot from an OpenFirmware
like flattened device tree. The PPC 4xx family of processors, as an
example, does not do this yet though there is work going on to adapt it.

Eventually, arch/ppc will go away and all of PowerPC will be under
arch/powerpc. That's the goal anyway.
