From ebc07025bfab21293805209cf5a14e4310c7993d Mon Sep 17 00:00:00 2001 From: Colin Cross Date: Wed, 7 Mar 2012 17:34:30 -0800 Subject: [PATCH] staging: android: ram_console: drop early buffer support Early ramconsole is not very useful, an early crash will prevent getting the logged data out on the next boot, and CONFIG_DEBUG_LL=y will get the same information. Drop it to simplify a future refactoring.
