Subject: [PATCH v2 08/10] powerpc/configs/skiroot: Disable xmon default & enable reboot on panic
Date: Tue, 21 Jan 2020 15:29:58 +1100	[thread overview]
Message-ID: <20200121043000.16212-8-mpe@ellerman.id.au> (raw)
In-Reply-To: <20200121043000.16212-1-mpe@ellerman.id.au>

If the skiroot kernel crashes we don't want it sitting at an xmon
prompt forever. Instead it's more helpful to reboot and bring the
boot loader back up, and if the crash was transient we can then boot
successfully.

Similarly if we panic we should reboot, with a short timeout in case
someone is watching the console.
