From 25ebee020bd34d1f4c5678538204f0b10bf9f6d5 Mon Sep 17 00:00:00 2001 From: Catalin Marinas Date: Tue, 25 Sep 2007 15:22:24 +0100 Subject: [ARM] 4583/1: ARMv7: Add VFPv3 support This patch adds the support for VFPv3 (the kernel currently supports VFPv2). The main difference is 32 double registers (compared to 16).
