commit 3b49791e4cc2f38dd84bf331b75217adaef636e3 Author: Bertrand Marquis <bertrand.marquis@xxxxxxx> AuthorDate: Fri Oct 16 14:58:47 2020 +0100 Commit: Stefano Stabellini <sstabellini@xxxxxxxxxx> CommitDate: Tue Oct 20 13:20:31 2020 -0700 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.
