X-Git-Tag: upstream/snapshot3+hdmi~14920^2~7
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=325ffc3633f1c30ef89d98d619f7e1497366e77c;p=platform%2Fadaptation%2Frenesas_rcar%2Frenesas_kernel.git

ARM: 5997/1: ARM: Correct the VFPv3 detection

A CPU has VFPv3 hardware if the FPSID[19:16] bits are 2 or more.
Currently Linux was only checking for 3 or more.
