From 56d611a04fb2db77334e06274de4daed92e2c626 Mon Sep 17 00:00:00 2001 From: Marco Stornelli Date: Wed, 26 May 2010 14:43:54 -0700 Subject: char drivers: RAM oops/panic logger Ramoops, like mtdoops, can log oops/panic information but in RAM. It can be used with persistent RAM for systems without flash support. In addition, for this systems, with this driver, it's no more needed add to the kernel the mtd subsystem with advantage in footprint. It can be used in a very easy way with persistent RAM for systems without flash support. For these systems, with this driver, it is no longer required to cinlude mtd subsystem with an advantage in footprint. In addition, you can save flash space and store this information only in RAM.
