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 Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>

|
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.

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.
