Subject: [PATCH 2/2] net: fec_imx: fix timeout off by *1000 error
Date: Fri, 14 Dec 2018 16:23:08 +0100 [thread overview]
Message-ID: <20181214152305.30412-2-a.fatoum@pengutronix.de> (raw)
In-Reply-To: <20181214152305.30412-1-a.fatoum@pengutronix.de>
read*_poll_timeout's final timeout parameter is in microseconds,
but the supplied arguments in fec_imx.c were in nanoseconds,
which might lead to barebox getting seemingly stuck in fec_halt
(loops for a thousand seconds instead of one).
I've tested this still works on an i.MX6D by copying a file over
TFTP and verifying the hash is correct.
