From 8f7f9435e6df0985c877d10259393bdfaac3655f Mon Sep 17 00:00:00 2001 From: Paul Gortmaker Date: Fri, 27 Oct 2006 05:13:19 +0100 Subject: [PATCH] [ARM] 3912/1: Make PXA270 advertise HWCAP_IWMMXT capability ARM patch 3756/1 added HWCAP_IWMMXT. This patch adds support for broadcasting that info via /proc/cpuinfo and sets it for the CPU features of the PXA270. I've booted 19rc3 on a pxa270 and confirmed that the /proc/cpuinfo shows "iwmmxt" in the Features.
