Suppose you have two network controllers.
The first one is ENC28J60 (it is in low power mode
after start) the second one is always-enabled eth1.
As ENC28J60 is in low power mode before enc28j60_eth_open()
is called. ENC28J60's mii traceiver is in low power mode too
so the mii traceiver's register are inaccessable.
Here is a sample log just after barebox start:
barebox:/ miitool
miibus0: registered phy as /dev/phy0
No MII transceiver present!.
miibus1: registered phy as /dev/phy1
phy1: eth1: negotiated 100baseTx-FD, link ok
barebox:/ miitool
No MII transceiver present!.
phy1: eth1: negotiated 100baseTx-FD, link ok
The 'No MII transceiver present!.' message is confusing here.

looks like this:

This patch does probably too much, but it's hard (and very
cumbersome/time consuming) to break it out. What is does is this:
* each command has one short description, e.g. "list MUX configuration"
* made sure the short descriptions start lowercase
* each command has one usage. That string contains just the
options, e.g. "[-npn]". It's not part of the long help text.
* that is, it doesn't say "[OPTIONS]" anymore, every usable option
is listed by character in this (short) option string (the long
description is in the long help text, as before)
* help texts have been reworked, to make them
- sometimes smaller
- sometimes describe the options better
- more often present themselves in a nicer format
* all long help texts are now created with BUSYBOX_CMD_HELP_
macros, no more 'static const __maybe_unused char cmd_foobar_help[]'
* made sure the long help texts starts uppercase
* because cmdtp->name and cmdtp->opts together provide the new usage,
all "Usage: foobar" texts have been removed from the long help texts
* BUSYBOX_CMD_HELP_TEXT() provides the trailing newline by itself, this
is nicer in the source code
* BUSYBOX_CMD_HELP_OPT() provides the trailing newline by itself
* made sure no line gets longer than 77 characters
* delibertely renamed cmdtp->usage, so that we can get compile-time
errors (e.g. in out-of-tree modules that use register_command()
* the 'help' command can now always emit the usage, even without
compiled long help texts
* 'help -v' gives a list of commands with their short description, this
is similar like the old "help" command before my patchset
* 'help -a' gives out help of all commands

Creating menus from the shell using the regular 'menu' command is rather
complicated. This adds a 'menutree' command which creates a menu from
a directory structure. In the directory structure each directory corresponds
to a single menu entry. The directory contains the following files:
title - A file containing the title of the entry as shown in the menu
box - If present, the entry is a 'bool' entry. The file contains a variable
name from which the current state of the bool is taken from and saved
to.
action - if present this file contains a shell script which is executed when
when the entry is selected.
If neither 'box' or 'action' are present this entry is considered a submenu
containing more entries.

The Bootloader Specification describes a way how kernels can
be installed on devices and how they can be started by the bootloader.
The bootloader spec is currently supported by (x86) gummiboot and
by systemd which provides a kernel-install script. With the bootloader
spec it's possible for the Operating system to install a new kernel
without knowing about the bootloader and for the bootloader it's possible
to discover and start Operating Systems on a media without being
configured.
For more details about the spec see:
http://www.freedesktop.org/wiki/Specifications/BootLoaderSpec/
This patch adds barebox support for the spec. It enhances the 'boot'
command so that not only boot script names can be given, but also
devices containing bootloader spec entries. With this it's possible
to call the 'boot' command like: 'boot sd emmc net'. It would then
first look for bootloader spec entries on the (removable) sd card,
then, is nothing is found, on the internal emmc and if still
unsuccessful would call the 'net' bootscript.
The bootloader Spec currently doesn't specify which entry should be
default if multiple entries are found on a single device. Therefore
barebox currently has two extensions of the spec. The $BOOT diretory
can contain a file named 'default'. If present, the content of the
file is treated as a filename under $BOOT/loader/entries/ which is
used as default. Similarly if a file named 'once' is present, the
entry is started once and the file is removed afterwards. This is
useful for testing if a newly installed kernel works before making
it the default.
As on ARM and other Architectures a devicetree has to be specified
for the kernel, the 'devicetree' property is used to specify a
devicetree. Like 'kernel' and 'initrd' this also contains a pth
relative to $BOOT.

With this a mount <devname> will mount the device to /mnt/<devname>. This
directory is created automatically if it doesn't exist already.

This replaces the 'boot' script in the defaultenv-2 with a command
with the same behaviour. A command gives more flexibility for future
externsions

It's useful to know which filesystems a barebox binary supports.
Add a -v option to the mount command to find it out.

When printing the devices on which a path is mounted the backingstore is
the interesting thing, not dev_name.
