I'm currently working on a PPC 405 based developement card. Does it mean I have to work using the arch/ppc tree ? What about the includes ? Do I have to use only include/asm-ppc or are include/asm-powerpc necessary as well ? > Eventually, arch/ppc will go away and all of PowerPC will be under > arch/powerpc.
