Subject: [PATCH] IBM PowerPC 750GX Support
Date: Wed, 12 May 2004 21:14:03 -0700 [thread overview]
Message-ID: <20040513041403.GA11357@staidm.org> (raw)
This patch adds preliminary support for the IBM PowerPC 750GX. In
summary this part is a PPC750FX ramped to 1 GHz with a 1MB 4-way L2
and more advanced I/O pipelining. It is beginning to appear in embedded
systems and was rumored to be under evaluation inside Apple. Tested on
PVR 70020101; please merge.
