In some cases it is practical to supervise as much as possible of
the barebox execution with a watchdog (or multiple watchdogs). This
patch provides an async poller for watchdog core framework which can
be enabled by the user and stores this configuration to nv.

timeout_cur will be used for watchdog poller.
Provided values should be good enough for most users
and still can be changed for separate projects and
fit to needed requirements.

the watchdog hwdev is usually named with devicetree schema
which is not practical for CLI.
On device registration "wdog" will be extended with some index number
extracted from devicetree (if awailable) or automatically assigned
first available number. End result will be "wdog0" .. etc.

The bootm code needs to read the beginning of the OS image in order to

Right now we only have the dma_sync_single_* functions, but no functions
for actually mapping a pointer. The mapping functions become necessary
when casting a pointer to unsigned long to get a dma address is not
enough. (I'm not even going so far that we'll add IOMMU support, but on
some architectures we need a place where we can check if a pointer is
DMA mappable at all)

This commit introduces support for running the md and mw commands
using the binary interface provided by RATP. This allows clients to
read and write memory files without needing to do custom string
parsing on the data returned by the console 'md' and 'mw' operations.
The request and response messages used for these new operations are
structured in the same way:
* An initial fixed-sized section includes the fixed-sized
variables (e.g. integers), as well as the size and offset of the
variable-length variables.
* After the initial fixed-sized section, the buffer is given, which
contains the variable-length variables in the offsets previously
defined and with the size previously defined.
The message also defines separately the offset of the buffer
w.r.t. the start of the message. The endpoint reading the message will
use this information to decide where the buffer starts. This allows to
extend the message format in the future without needing to break the
message API, as new fields can be appended to the fixed-sized section
as long as the buffer offset is also updated to report the new
position of the buffer.
E.g.:
$ ./bbremote --port /dev/ttyUSB2 md /dev/pic_eeprom_rdu 0x107 5
0000000000
$ ./bbremote --port /dev/ttyUSB2 mw /dev/pic_eeprom_rdu 0x107 0102030405
5 bytes written
$ ./bbremote --port /dev/ttyUSB2 md /dev/pic_eeprom_rdu 0x107 5
0102030405
$ ./bbremote --port /dev/ttyUSB2 mw /dev/pic_eeprom_rdu 0x107 0000000000

$ ./bbremote --port /dev/ttyUSB2 md /dev/pic_eeprom_rdu 0x107 5

The RATP implementation now allows executing generic commands with a
binary interface: binary requests are received and binary responses
are returned.
Each command can define its own RATP request contents (e.g. to specify
command-specific options) as well as its own RATP response contents
(if any data is to be returned).
Each command is associated with a pair of numeric unique request and
response IDs, and for easy reference these IDs are maintained in the
common ratp_bb header. Modules may override generic implemented
commands or include their own new ones (as long as the numeric IDs
introduced are unique).

Custom projects may need vendor specific expansions to the fastboot
command execution. Allow these to be implemented without messing in
the fastboot code directly.
We have a hook for all commands and also one for the "flash" command.
Each hook can decide if the generic command parser is executed
afterwards (return value FASTBOOT_CMD_FALLTHROUGH) or if the generic
parser shall be skipped (return value 0 or negative error code).
This allows board code to implement vendor specific "oem" commands
or to handle the downloaded image in a special way (i.e. do signature
checks on them)

Due to the nature of TFTP which can't lseek and due to the silliness
of our filesystem implementation which can't cache accesses we have to
manually cache files on TFTP filesystems sometimes. Make it easier
for them by providing a cache_file() function which copies the file
from TFTP to RAM.

Create a make_temp() function which creates a name for a temporary file.
Since we do not have any concurrency in barebox we do not need to create
the file right away and can leave that to the caller. Unlike unix
mktemp the resulting filename is dynamically allocated and must be
freed by the caller.

Some commands need files in which they can lseek backwards which
is particularly not possible on TFTP. Instead of hiding this
behind can_lseek_backward() create a function for it which tests
if the file is on TFTP directly rather than using different
lseek operations.

This adds support for const properties. We add a const void *value_const
to struct property which will not be modified. The value of a property
should no longer be used directly, but with the of_property_get_value()
accessor which picks the right value.
With this we can unflatten dtbs and use the property values directly
from the dtb instead of copying them. This is useful for device trees
which (ab)use properties to store huge data files, aka FIT images.
To create a property whose value is not copied but used from the
original input data we introduce of_new_property_const().
