From 88965fef6ef005df15e6fac8d2e33fd775a1466d Mon Sep 17 00:00:00 2001 From: =?utf8?q?Pali=20Roh=C3=A1r?= Date: Tue, 9 Mar 2021 14:26:57 +0100 Subject: [PATCH] arm: mvebu: Espressobin: Enable watchdog support but do not start it MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Espressobin had disabled watchdog support (CONFIG_WDT) because older stable Linux kernel versions (which are used by current stable OpenWRT and Debian versions) do not have support for Armada 3700 watchdog driver. Therefore they are not able to periodically kick watchdog so Espressobin enter into boot loop. This change enable CONFIG_WDT, CONFIG_WDT_ARMADA_37XX and CONFIG_CMD_WDT options which add support for U-Boot 'wdt' command. And unset new CONFIG_WATCHDOG_AUTOSTART option which cause that watchdog is not automatically started by U-Boot during init phase, like when CONFIG_WDT option is not set at all. So with this change, U-Boot on Espressobin would have working 'wdt' command which can be used from boot scripts (e.g. for enabling watchdog prior new Linux booting kernel). But default behavior of watchdog status stays unchanged, U-Boot does not start watchdog on Espressobin during its init phase.
