[PATCH] powerpc: Better machine descriptions and kill magic numbers
Benjamin Herrenschmidt
benh at kernel.crashing.org
Sat Jan 14 16:45:30 EST 2006
This patch does the long awaited change of the machine descriptions so
that:
- Both 32 and 64 bits now rely on a probe() entrypoint in ppc_md which
is supposed to use the flat device-tree to identify the board. In
addition, I've added a couple of functions to make things easier to
retreive the root of the flat device-tree and to test the "compatible"
property of a node in the flat tree
- Machines are defined entirely locally to the machine setup*.c file. A
macro is used to define the ppc_md structure for the board and adds it
to a specific ELF section. It will automatically get probed.
- Machines/Platforms magic numbers are gone, _machine is gone too, you
can now use the machine_is(name) macro to check if you are running on a
givem board, this macro works by testing which of the machine
descriptions was selected at boot.
- I kept the !MULTIPLAFORM case available for 32 bits (in which case
you still have to provide a platform_init() routine) but I would like
that to go. I recommend that any new and/or embedded board ported to
ARCH=powerpc gets added to the MULTIPLATFORM case. If necessary, Kconfig
should be fixed to enable MULTIPLATFORM for other CPU types.
Tested on 32 and 64 bits powermacs and pseries. Build tested on iseries
chrp and maple.
