From 40fb9b05831468a33529094cbd8d27a495a88704 Mon Sep 17 00:00:00 2001 From: Gabor Juhos Date: Tue, 25 Sep 2012 12:57:41 +0000 Subject: [PATCH] ar71xx: create 'fat' images for the DIR-825/TEW-673GRU boards With these images, it is possible to use the 'unused' partition of the flash. The 'fat' images can be installed with the sysupgrade command. When a 'fat' image is installed from a regular one, the platform specific sysupgrade script copies the calibration data to the end of the flash. Likewise, when a regular image is installed from the 'fat' version the sysupgrade script copies the calibration data back to the original location.
