Not really. PMAC systems are not being built any more.

This problem is solved with defconfigs. Kconfig options are supposed to make sense. Not all PowerPC systems are CHRP, therefore CHRP should not be enabled by default. > But, turning them all on would not matter.

Having the default be disabled for specific platforms can make a big difference in compile time. > but you would be guaranteed to get a kernel > binary somewhere in the tree that would work on all of them :) Again, not relevant. One giant kernel that works on a Freescale embedded system *and* an IBM mainframe is useless. No one would actually ever do that. > Genesi, Manager, Developer Relations Developer Relations, eh? -- Timur Tabi Linux kernel developer at Freescale _______________________________________________ Linuxppc-dev mailing list Linuxppc-dev@ozlabs.org https://ozlabs.org/mailman/listinfo/linuxppc-dev
