From d9f5007491e3b6693dd00487981676b6b3005d72 Mon Sep 17 00:00:00 2001 From: vikram pandita Date: Sun, 22 Nov 2009 10:10:49 -0800 Subject: omap: introduce OMAP_LL_DEBUG_NONE DEBUG_LL config Zoom2/Zoom3 kind of boards do not use omap uarts for console. These use external debug board for console. So these boards should not have "Uncompressing Kernel...." log put on omap uarts. By interoducing OMAP_LL_DEBUG_NONE option, unnecessary writes to omap uarts is avoided. In future, the DEBUG_LL interface will be enhanced to use external debug board.
