From 8846830e0f7b5ea2721e3d8b2bd517fa1a11c628 Mon Sep 17 00:00:00 2001 From: Andy Green Date: Thu, 11 Sep 2008 20:38:46 +0800 Subject: [PATCH] fix-glamo-crank-memory-to-90MHz.patch This changes Glamo memory and now host bus PLL to 90MHz from 80MHz, as recommended by S-Media. Bandwidth should go up by 12.5% by this in raw terms anyway.
