oftree command: retire CMD_OFTREE_PROBE Kconfig option ...

Whether or not the user wishes devicetree probe support can
now be decided indepentently of the oftree command, so retire
the CMD_OFTREE_PROBE option and use OFDEVICE in the code instead.

of: make OFDEVICE a user selectable option ...

OFDEVICE decides whether or not we compile in support for probing
devices from the devicetree. Let the user decide this explicitly.
This makes the oftree, of_node and of_property commands independent
of devicetree device support since being able to manipulate
devicetrees has nothing to do with probing devices from the devicetree.

this will allow to have no console support

Use full for bootstrap as we can save 6.5 KiB (barebox.bin) and

As on bootstrap we have often very limited size.

oftree command: refactor ...

This has several improvements for the oftree command:

- loading a devicetree (-l) and actually probing (-p) it now is separated
- the command now can dump the internal devicetree or a dtb given on the
  command line.
- The -f option now actually frees the internal devicetree

With this the usage pattern for this command is:

oftree -l /env/oftree

oftree -d -n /sound

oftree -d /env/oftree

oftree -f

oftree -p

oftree -l -p /env/oftree

commands: change Y-Modem implementation ...

The current Y-Modem implementation has some limitations:
 - Y-Modem/G protocol is not supported
 - Multiple files (aka. batch) transfers are not supported
 - Transfer speed over fast lines (USB console) is slow
 - Code is not trivial to maintain (personnal opinion)

This implementation tries to address all these points by
introducing loady2 command.

The effects are :
 - transfer speed for Y-Modem over USB jumps from 2kBytes/s
   to 180kBytes/s
 - transfer speed for Y-Modem/G jumps to 200kBytes/s
 - multiple file transfers are possible

This command was tested on a USB console and UART 9600bps
serial line :
 - NAKs (and retransmissions) were tested for faulty
   serial lines
 - multiple file transfers were tested
 - Y-Modem, Y-Modem/G and X-Modem transfers were tested

This adds support for a filetype detection command. It can be

The command also has an option to print the known filetypes
so that a user knows what to match for.

add 'miitool' command to view media-independent interface status ...

This command is based on the 'mii-diag' and 'mii-tool'
Unix utilities, but it lacks routines to manipulate
MII state (e.g. reset MII, restart autonegotiation
or force MII mode).

This version of the 'miitool' command has no GbE support,
but we can upgrade it in the future. The GbE support
patch for generic 'mii-tool' is here

Add in-system barebox update infrastructure ...

Currently in-system update means to write an arbitrary file to
an arbitrary device. There is no sanity check if the flashed image
is of the right type or will fit onto the device. Furthermore some
SoCs need a special preparation step for their images before
flashing them.

This adds a barebox in-system update infrastructure. Boards can
register update handlers which know how to make the board bootable.
The available handlers can be listed to be able to select one,
different force levels give the user the chance to know it better.

net: Add tftp command which uses the new tftp code ...

Traditionally tftp is a command of its own. Since we can
mount tftp as a filesystem we have duplicated the tftp code, the old
code is used by the tftp command, the new by the filesystem support.
This adds a tftp command based on the filesystem support to preserve
backward compatibility. This allows us to remove the old tftp support
in the next step.
