Because they are by far the historically most common configuration, and
still in production as the defacto standard PowerPC system configuration.
So you could make an argument for it being turned on in
arch/powerpc/defconfig, if we had one. That doesn't mean it should be
"default y".
IBM blades etc. with SLOF will boot up as a CHRP-ish system, as well as the
Efika and Pegasos and anything else Genesi produces. Since Linux
distributions
generally do not support tiny embedded boards,
What do distributions have to do with it? It's harder for distributions
to set the options they want than for embedded developers?
you can imagine why it's
disabled by default, but there's no reason it can't be ENABLED by default
and turned off by a distribution, the same way it can't be enabled by
default and turned off by YOU (compare and contrast having to manually
select which board you want to build for every time).
Likewise there's no reason that PMAC/CHRP can't be DISABLED by default,
and turned on by YOU.
But, turning them all on would not matter. You would build a kernel for
every one and a device tree for every one increasing your build time a
bit for a default kernel,
s/a bit/a lot/
but you would be guaranteed to get a kernel
binary somewhere in the tree that would work on all of them :)
Really? Who do I go to for this guarantee, when there's no support for
the hardware I'm trying to get to work? :-)
