From eda0ba38a8dfd2572089bd229a027d497c340158 Mon Sep 17 00:00:00 2001 From: Heiko Schocher Date: Mon, 4 Nov 2013 14:04:59 +0100 Subject: bootcount: store bootcount var in environment If no softreset save registers are found on the hardware "bootcount" is stored in the environment. To prevent a saveenv on all reboots, the environment variable "upgrade_available" is introduced. If "upgrade_available" is 0, "bootcount" is always 0 therefore no need to save the environment on u-boot boot, if "upgrade_available" is 1 "bootcount" is incremented in the environment and environment gets written on u-boot start. So the Userspace Applikation must set the "upgrade_available" and "bootcount" variable to 0 (for example with fw_setenv), if a boot was successfully.
