Subject: [U-Boot] [PATCH] configs: icorem6: Use imx6 cratch register for bootcount
Date: Thu, 21 Mar 2019 14:05:53 +0530	[thread overview]
Message-ID: <20190321083553.4068-1-jagan@amarulasolutions.com> (raw)

SRAM address used for bootcount on exiting code is erasing
previous count value when system reset from Linux. So use
the dedicated imx6 scratch register, GPR2 to preserve the
contents even if the system reset from Linux.

Fixes: 4eb9aa39350e ("configs: imx6qdl_icore_mmc: Enable watchdog and bootcounter")
