From 3b49791e4cc2f38dd84bf331b75217adaef636e3 Mon Sep 17 00:00:00 2001 From: Bertrand Marquis Date: Fri, 16 Oct 2020 14:58:47 +0100 Subject: [PATCH] xen/arm: Print message if reset did not work If for some reason the hardware reset is not working, print a message to the user every 5 seconds to warn him that the system did not reset properly and Xen is still looping. The message is printed infinitely so that someone connecting to a serial console with no history would see the message coming after 5 seconds.
