Subject: [PATCH 3/4] powerpc/booke64: Use appropriate -mcpu
Date: Tue, 20 Aug 2013 21:12:41 -0500 [thread overview]
Message-ID: <1377051162-2588-4-git-send-email-scottwood@freescale.com> (raw)
In-Reply-To: <1377051162-2588-1-git-send-email-scottwood@freescale.com>
By default use -mcpu=powerpc64 rather than -mtune=power7
Add options for e5500/e6500, with fallbacks for older compilers.
Hide the POWER cpu options in booke configs.
