In the kernel for PPC, a lot a code is here just to do what doing RTAS :
pci config,
via (CUDA and PMU) (no need if no ADB keyboard), ...
When doing embedded systems, this drivers is very big and can be saving by
using
RTAS which i think is a very good thing in CHRP specification. It's
strange that
apple do not provide it fully.
Well, they didn't care about it. Note that Macs are far from beeing
embedded boxes ;)
