From efe90d273b6f365d37c0f82fbbd68a40982c3265 Mon Sep 17 00:00:00 2001 From: Russell King Date: Fri, 8 Dec 2006 15:22:20 +0000 Subject: [ARM] Handle HWCAP_VFP in VFP support code Don't set HWCAP_VFP in the processor support file; not only does it depend on the processor features, but it also depends on the support code being present. Therefore, only set it if the support code detects that we have a VFP coprocessor attached. Also, move the VFP handling of the coprocessor access register into the VFP support code.
