Subject: [PATCH 2/5] powerpc: Introduce CONFIG_PPC_BOOK3S
Date: Wed, 03 Jun 2009 17:17:37 +1000	[thread overview]
Message-ID: <20090603071752.5BB91DDDF7@ozlabs.org> (raw)
In-Reply-To: <1244013451.727669.180978693322.qpush@grosgo>

This patch introduce a new Kconfig option, CONFIG_PPC_BOOK3S
that represents processors that are compliant with the "classic"
(aka "server") variant of the PowerPC architecture.

It replaces CONFIG_6xx on 32-bit (though the symbol is still
defined for compatibility) and encompass all currently supported
64-bit processors.
