Subject: [PATCH 2/6] powerpc: Move CONFIG_PPC64 into CPU selection
Date: Wed, 02 May 2007 13:47:11 +0200 [thread overview]
Message-ID: <20070502115644.764580297@arndb.de> (raw)
In-Reply-To: 20070502114709.074174446@arndb.de
Currently, PPC64 is a top level configuration option in
arch/powerpc/Kconfig, which is somewhat unconventional.
Moving it into the CPU selection menu is a natural choice,
and is transparent to the rest of the configuration logic.

There are four families of PowerPC chips supported. The more common

- versions (821, 823, 850, 855, 860, 52xx, 82xx, 83xx), the AMCC
- embedded versions (403 and 405) and the high end 64 bit Power
- processors (POWER 3, POWER4, and IBM PPC970 also known as G5).

- This option is the catch-all for 6xx types, including some of the
- embedded versions. Unless there is see an option for the specific
