From: Alexander Graf Date: Tue, 9 Feb 2010 16:37:02 +0000 (+0100) Subject: PPC: Use Mac99_U3 type on ppc64 X-Git-Tag: TizenStudio_2.0_p2.3.2~208^2~8710^2~10 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=0f921197f1a83e4fe6e71a9edef7e2a0afb712b7;p=sdk%2Femulator%2Fqemu.git PPC: Use Mac99_U3 type on ppc64 The "Mac99" type so far defines a "U2" based configuration. Unfortunately, there have never been any U2 based PPC64 machines. That's what the U3 was developed for. So let's split the Mac99 machine in a PPC64 and a PPC32 machine. The PPC32 machine stays "Mac99", while the PPC64 one becomes "Mac99_U3". All peripherals stay the same. Signed-off-by: Alexander Graf Signed-off-by: Michael S.
