Add initial regulator support ...

Provide minimal regulator support. Only supported operations are enabling
and disabling regulators. Association of devices with their regulators is
limited to devicetree only. If regulator support is disabled the API expands
to static inline stubs so consumers can still use the API.

add menutree command ...

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.

Add readf command ...

The readf command is useful to read the content of a file into
a shell variable. It should be used for ascii content and thus
stops reading at all nonprintable characters including newline.

commands: add new memtest command ...

This new memtest can test the whole unused memory. The new memtest
command try to request the whole unused sdram regions on all banks and
run the mem_test routine from common/memtest.c on it.

The memtest command has only two parameters;
  -i	Amount of iterations, default 1, iteration of 0 is endless.
  -b	Set this to skip integrity check.(Do only a fast test for bus lines)

If MMU support is enable, memtest try to run memtest twice. The first with
cache enabled, the second with cache disabled.

devices: add detect mechanism ...

We often encounter the situation where slow devices should not be
probed during startup since probing is slow and maybe unnecessary
for unused devices. With MMC we have the 'probe' device parameter,
for ata we have the same, for USB we have the 'usb' command. Overall
this is not very consistent.
With MMC there is the additional problem that the probe parameter
is attached to the logical device when we often have the information
which physical device we want to probe.
This patch adds a 'detect' callback for devices and adds a command
to detect devices and to list the devices which are actually detecable.

Add memory modify command (mm) ...

As of now we have no way to manipulate individual bits of registers on the
command line. This introduces a memory modify command which allows this. It
has the syntax:

mm [OPTIONS] <adr> <val> <mask>

With [OPTIONS] being the usual memory command options (-b, -w, -l, -d <file>).

memory commands: separate into one file per command ...

Normally in commands we have one file per command which is named like
the command itself. The memory commands are an exception to this. This
patch changes this by separating the memory commands. This also has the
effect that the memory commands can now be selected individually. Along
the way we add some Kconfig help text for the commmands.

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

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
