[PATCH] ppc32: Remove CONFIG_PMAC_PBOOK
This patch removes CONFIG_PMAC_PBOOK (PowerBook support). This is now
split into CONFIG_PMAC_MEDIABAY for the actual hotswap bay that some
powerbooks have, CONFIG_PM for power management related code, and just left
out of any CONFIG_* option for some generally useful stuff that can be used
on non-laptops as well.

- ---help---
- This provides support for putting a PowerBook to sleep; it also
- enables media bay support. Power management works on the
- PB2400/3400/3500, Wallstreet, Lombard, and Bronze PowerBook G3 and
- the Titanium Powerbook G4, as well as the iBooks. You should get
- the power management daemon, pmud, to make it work and you must have
- the /dev/pmu device (see the pmud README).
-
- Get pmud from <ftp://ftp.samba.org/pub/ppclinux/pmud/>.
-
- If you have a PowerBook, you should say Y here.
-
- You may also want to compile the dma sound driver as a module and
- have it autoloaded. The act of removing the module shuts down the
- sound hardware for more power savings.

+ try with
