The current implementation fakes a memory-mapped I/O device
at 0x3f8 and 0x2f8, then uses platform read/write functions
to do the actual reading and writing. These platform functions
only exist for the x86 platform; better to move the I/O
routines into the driver and have the driver request I/O ports
using request_ioport_region.

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.

MTD internal API presently uses 32-bit values to represent device
size. This patch updates them to 64-bits but leaves the external API
unchanged.
In general, changing from 32-bit to 64-bit values cause little
or no changes to the majority of the code with the following
exceptions:
- printk message formats;
- division and modulus of 64-bit values (mtd_div_by_wb,
mtd_div_by_eb may be used in some of such cases).

The default nand_read_subpage implementation returns -ENOSUPP, so we have
to make sure that barebox never uses this implementation. By setting the
NAND_SUBPAGE_READ flag to 0x0 we ensure NAND_HAS_SUBPAGE_READ() never returns
true and also give the compiler a chance to optimize away some unused code.
subpage reads are a rather exotic feature even in Linux. It is only used on
largepage NANDs with soft ecc. Even if we have this case it needs non page
aligned reads to actually profit from this feature.

Compared to devfs_add_partition which adds a single partition
devfs_create_partitions creates several partitions at once. One nice
benefit is that this simplifies appending partitions because the start
of the latter partition doesn't need to be specified explicitly.
Also dev_add_bb_dev() is called by the new helper if the bbname is
specified for a partition.
Note that adding partitions is also more flexible now (also via
devfs_add_partition) because negative values for offset and size now
have a proper meaning instead of creating broken partitions.

Currently the version defines reflect the digits in the version
number. MMC_VERSION_4_41 is defined as 0x441 and MMC_VERSION_4_5
is defined as 0x405. This results in MMC_VERSION_4_5 < MMC_VERSION_4_41
becoming true which was surely not intended. Fix this by
redefining the versions as 0x<major><minor><micro>. This makes the
string generation more complicated but makes versions comparable
again.

On some architectures (e.g. alpha, amd64, arm64, ia64, s390x, mips64)
sizeof(ulong) is 8 which made net_read_uint32 actually read too much and
even returned the wrong value on big endian machines.
(Note the second issue isn't that critical though, because the only
architecture from the list above that uses big endian byte order is s390x
...)
Also change the argument to void * because the pointer is not necessarily
properly aligned.

Linux specifies the linux,stdout-path property in the /chosen node
in the devicetree. Unfortunately this is ignored in most cases.
For cases in which barebox uses this property for its own use we
translate this into a Linux boot arg with:
- the console name provided by the serial driver
- the the instance from the 'serial' alias
- the baudrate from the actual baudrate.
So with this it's for devicetee enabled boards no longer necessary
to manually assign a console= parameter. Should a user not want
to use the automatically assigned parameter it should do:
global.linux.bootargs.console=
in the environment.
