Benjamin Herrenschmidt 28794d34ec powerpc/kconfig: Kill PPC_MULTIPLATFORM
CONFIG_PPC_MULTIPLATFORM is a remain of the pre-powerpc days and isn't
really meaningful anymore. It was basically equivalent to PPC64 || 6xx.

This removes it along with the following changes:

 - 32-bit platforms that relied on PPC32 && PPC_MULTIPLATFORM now rely
   on 6xx which is what they want anyway.

 - A new symbol, PPC_BOOK3S, is defined that represent compliance with
   the "Server" variant of the architecture. This is set when either 6xx
   or PPC64 is set and open the door for future BOOK3E 64-bit.

 - 64-bit platforms that relied on PPC64 && PPC_MULTIPLATFORM now use
   PPC64 && PPC_BOOK3S

 - A separate and selectable CONFIG_PPC_OF_BOOT_TRAMPOLINE option is now
   used to control the use of prom_init.c

bool "Support for PReP Residual Data"
depends on PPC_PREP
help
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.
config PROC_PREPRESIDUAL
bool "Support for reading of PReP Residual Data in /proc"
depends on PREP_RESIDUAL && PROC_FS
help
Enabling this option will create a /proc/residual file which allows
you to get at the residual data on PReP systems. You will need a tool
(lsresidual) to parse it. If you aren't on a PReP system, you don't
want this.
