Subject: [PATCH 07/16] fastboot: handle ill-named partitions gracefully
Date: Mon,  3 May 2021 13:48:52 +0200	[thread overview]
Message-ID: <20210503114901.13095-8-a.fatoum@pengutronix.de> (raw)
In-Reply-To: <20210503114901.13095-1-a.fatoum@pengutronix.de>

Users can configure a partition name of bbu-something that would
conflict at fastboot init time with a barebox update "something"
handler. Current behavior is to silently ignore all remaining
barebox update handlers.

It would be better to complain loudly and to skip only the entries
actually conflicting. Do so.
