fs: Add super_operations ...

Add a struct super_operations we can use later when we get a fs
implementation closer to Linux. Only add the functions we'll likely
need though.

rename file_operations -> cdev_operations ...

Linux also has struct file_operations which are something different.
Rename our file_operations to cdev_operations which better matches
what we have.

bootm: provide handlers the start of the OS image ...

The bootm code needs to read the beginning of the OS image in order to
determine the filetype. If it does so already, then we can provide the
handlers the buffer. This can help the handlers to find some image
metadata before loading the full image.

common: Add functions to find free RAM ...

aiodev: Constify 'unit' in 'struct aiodev' ...

The way it is currently used, there's no reason for 'uint' field to be
mutable, so constify it in order to allow 'aiodev' drivers to pass
sting literals in that field.

dma: Add prototypes for dma mapping functions ...

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)

dma: Use dma_addr_t as type for DMA addresses ...

DMA addresses are not necessarily the same as unsigned long. Fix
the type for the dma_sync_single_* operations.

watchdog: add watchdog poller ...

In some cases it is practical to supervise as much as possible of

patch provides an async poller for watchdog core framework which can
be enabled by the user and stores this configuration to nv.

ratp: new md and mw commands ...

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
    5 bytes written

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

ratp: implement generic command support ...

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).
