[2.6 patch] powerpc: remove the non-functional PPC_PREP bits

From: Adrian Bunk
Date: Sun Mar 30 2008 - 18:41:24 EST


Back in November 2005, the PPC_PREP bits under arch/powerpc/ were marked
as BROKEN due to not being working.

It doesn't seem to make much sense to keep this rudimentary support even
longer.

- Some PReP systems have residual data passed to the kernel by the
- firmware. This allows detection of memory size, devices present and
- other useful pieces of information. Sometimes this information is
- not present or incorrect, in which case it could lead to the machine
- behaving incorrectly. If this happens, either disable PREP_RESIDUAL
- or pass the 'noresidual' option to the kernel.

- If you are running a PReP system, say Y here, otherwise say N.

- Enabling this option will create a /proc/residual file which allows

- (lsresidual) to parse it. If you aren't on a PReP system, you don't
- want this.
