From ecab0cfe25600ad13c174b78a637515943cc870a Mon Sep 17 00:00:00 2001 From: David Brownell Date: Fri, 13 Nov 2009 16:58:14 -0800 Subject: [PATCH] ARM11: ETM + ETB support Kick in ETM (and ETB) support for ARM11. Tested on OMAP 2420, so update that configuration. (That's an ARM1136ejs, ETB, OpenGL ES1.1, C55x DSP, etc.) Also update the other ARM11 ETM + ETB targets in the tree to set up these modules. (Not tested.)
