Just breaking out of the loop results in ignoring the error. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de> Sascha Hauer committed on 6 May 2020

2020-03-31	af59178 Browse files » net: fec_imx: Do not clear MII interrupt during receive ... fec_recv() can be triggered during a MDIO access. so we may not clear the FEC_IEVENT_MII interrupt the MDIO access is waiting for. Clearing it in that moment causes the MDIO access to timeout. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de> Sascha Hauer committed on 31 Mar 2020

2019-02-11	55765b9 Browse files » net: fec_imx: skip fec_halt if the FEC wasn't started ... If the FEC driver is enabled, but the ethernet device was never opened due to booting from another source the wait for graceful transmit stop will always fail. This introduces an unnecessary boot delay and prints a distracting warning. As there is no point in trying to shut down the FEC if it was never started, just skip all of fec_halt in that case.

2018-12-17	943d690 Browse files » net: fec_imx: fix timeout off by 1000 error ... 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.

Trying to do unaligned access of coherent memory on AArch64 will lead to an abort and some parts of our IP stack will do exactly that with received packet buffer by using memcpy() to extracts parts of it. Convert the driver to use regular memory for received data buffers to prevent the issue from happening.
