From 62892b2f685f12b78a83ee90b847f875c2388b1d Mon Sep 17 00:00:00 2001 From: Darren Hart Date: Tue, 6 Sep 2011 09:39:17 -0700 Subject: [PATCH] beagleboard: document how to enable the hard floating point abi Closes [YOCTO #1203] Using the hard floating point abi is incompatible with some binary libaries and 3D support for the Beagleboard. While we do not provide these in poky and meta-yocto, softfp should remain the default for compatibility reasons. Provide documentation and a commented assignment to DEFAULT_TUNE instructing how to enable hardfp, but leave it disabled by default.
