net: Add new wol command - Wake on LAN

2018-07-02T19:14:20+00:00

Add a new command 'wol': Wait for an incoming Wake-on-LAN packet or
time out if no WoL packed is received.
If the WoL packet contains a password, it is saved in the environment
variable 'wolpassword' using the etherwake format (dot or colon
separated decimals).

Intended use case: a networked device should boot an alternate image.
It's attached to a network on a client site, modifying the DHCP server
configuration or setup of a tftp server is not allowed.
After power on the device waits a few seconds for a WoL packet. If a
packet is received, the device boots the alternate image. Otherwise
it boots the default image.

This method is a simple way to interact with a system via network even
if only the MAC address is known. Tools to send WoL packets are
available on all common platforms.

Some Ethernet drivers seem to pad the incoming packet. The additional
padding bytes might be recognized as Wake-on-LAN password bytes.

By default enabled in pengwyn_defconfig.

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: Make CMD_NET a menuconfig

2018-04-13T20:47:57+00:00

Previously, CMD_NET was an alias for 2 commands (bootp and tftpboot) and
they we not able to be disabled. Separate out those 2 commands and move
CMD_NET up to the menu level, which more accurately represents the code.

net: Disable the format-extra-args warning

2017-05-12T12:37:40+00:00

We will see warnings such as:
net/eth_common.c:57:61: warning: data argument not used by format string [-Wformat-extra-args]
        sprintf(enetvar, index ? "%s%daddr" : "%saddr", base_name, index);
                                              ~~~~~~~~             ^
With clang.  In this case we do not want to re-write our code to be less
compact as the above is intentional and readable.  Add a comment above
the disabling so that it's clear why we want that warning off.
