net: Initialize as many ethernet devices as possible

2018-06-13T18:54:15+00:00

On devices that have their first network interface provided by a FPGA,
the initialization of further interfaces will fail if the FPGA is not
yet programmed. This leads to problems during factory setup when the
data is supposed to be loaded over secondary netowork interfaces.

To avoid this, use the uclass_{first,next}_device_check functions to
initialize as many ethernet devices as possible.

SPDX: Convert all of our single license tags to Linux Kernel style

2018-05-07T13:34:12+00:00

When U-Boot started using SPDX tags we were among the early adopters and
there weren't a lot of other examples to borrow from.  So we picked the
area of the file that usually had a full license text and replaced it
with an appropriate SPDX-License-Identifier: entry.  Since then, the
Linux Kernel has adopted SPDX tags and they place it as the very first
line in a file (except where shebangs are used, then it's second line)
and with slightly different comment styles than us.

In part due to community overlap, in part due to better tag visibility
and in part for other minor reasons, switch over to that style.

This commit changes all instances where we have a single declared
license in the tag as both the before and after are identical in tag
contents.  There's also a few places where I found we did not have a tag
and have introduced one.

net: Only access network devices after init

2018-03-22T20:05:31+00:00

In the efi_loader main loop we call eth_rx() occasionally. This rx function
might end up calling into devices that haven't been initialized yet,
potentially resulting in a lot of transfer timeouts.

Instead, let's make sure the ethernet device is actually initialized before
reading from or writing to it.

env: Rename eth_getenv_enetaddr() to eth_env_get_enetaddr()

env: Rename getenv/_f() to env_get()

2017-08-16T12:30:24+00:00

We are now using an env_ prefix for environment functions. Rename these
two functions for consistency. Also add function comments in common.h.

Quite a few places use getenv() in a condition context, provoking a
warning from checkpatch. These are fixed up in this patch also.

net: core: avoid possible NULL pointer dereference

2017-06-02T19:44:19+00:00

Checking if dev is NULL after dereferencing it does not make sense.

net: core: cosmetic: A MAC address is not limited to SROM

2017-02-07T16:54:32+00:00

Currently, we print that the MAC from the SROM does not match. It can be
many forms of ROM, so lets drop the S.

net: cosmetic: Do not use magic values for ARP_HLEN

2017-02-07T16:54:32+00:00

Commit 674bb249825a ("net: cosmetic: Replace magic numbers in arp.c with
constants") introduced a nice define to replace the magic value 6 for
the ethernet hardware address. Replace more hardcoded instances of 6
which really reference the ARP_HLEN (iow the MAC/Hardware/Ethernet
address).

net: use random ethernet address if invalid and not zero

2016-11-07T17:28:16+00:00

Use random ethernet address if the ethernet address found
is invalid, not zero and config for random address
is defined.
