After any node/property deletion the device tree can be packed to remove
spare space. Add a way to perform this operation.
Note that for fdt_fallback, fdtput automatically packs the device tree after
deletion, so no action is required here.

Add support for deleting a device tree property. With the fallback
implementation this uses fdtput. With libfdt it uses the API call and
updates the offsets afterwards.

Since we want to be able to change the in-memory device tree using libfdt,
use a bytearray instead of a string. This makes interfacing from Python

When tools want to display information of varying levels of importance, it
helps to provide the user with control over the verbosity of these messages.
Progress messages work best if they are displayed and then removed from the
display when no-longer relevant.

At present we have two separate implementations of the Fdt library, one which
uses fdtget/fdtput and one which uses libfdt (via swig).
Before adding more functionality it makes sense to create a base class for
these. This will allow common functions to be shared, and make the Fdt API
a little clearer.
Create a new fdt.py file with the base class, and adjust fdt_normal.py and

The moveconfig tool is quite clever and generally produces results that

Prior to this commit, the tool could not move options guarded by
CONFIG_SPL_BUILD ifdef conditionals because they do not show up in
include/autoconf.mk. This new option, if given, makes the tool
parse spl/include/autoconf.mk instead of include/autoconf.mk,
which is probably preferred behavior when moving options for SPL.

Currently, the tool gives up moving an option quietly if its entry
was not found in Kconfig.
If the option is not defined in the config header in the first
place, it is no problem (as the Kconfig entry may have been hidden
by reasonable "depends on").
However, if the option is defined in the config header, the missing
Kconfig entry is a sign of possible behavior change. It is highly
recommended to manually check if the option has been moved as
expected. In this case, let's add "suspicious" in the log and
change the log color (if --color option is given) to make it stand
out.
This was suggested by Tom in [1].

56086921 added support for unaligned environments access.
U-boot itself does not support this:
- env_nand.c fails when using an unaligned offset. It produces an
error in nand_erase_opts{drivers/mtd/nand/nand_util.c}
- in env_sf/env_flash the unused space at the end is preserved, but
not in the beginning. block alignment is assumed
- env_sata/env_mmc aligns offset/length to the block size of the
underlying device. data is silently redirected to the beginning of
a block
There is seems no use case for unaligned environment. If there is
some useful data at the beginning of the the block (e.g. end of u-boot)
that would be very unsafe. If the redundant environments are hosted by
the same erase block then that invalidates the idea of double buffering.
It might be that unaligned access was allowed in the past, and that
people with legacy u-boot are trapped. But at the time of 56086921
it wasn't supported and due to reasons above I guess it was never
introduced.
I prefer to remove that (unused) feature in favor of simplicity

We mostly move config options from board header files to Kconfig,
but sometimes config defines come from CONFIG_SYS_EXTRA_OPTIONS.
Historically, CONFIG_SYS_EXTRA_OPTIONS originates in boards.cfg,
which was used as a central database of configuration prior to the
Kconfig conversion.
Now, we want to migrate to primary entries in Kconfig rather than
option list in CONFIG_SYS_EXTRA_OPTIONS, so it should be helpful to
have the tool to cleanup CONFIG_SYS_EXTRA_OPTIONS automatically.

The tools/moveconfig.py has a feature to cleanup #define/#undef's
of moved config options, but I want this tool to do a better job.
For example, when we are moving CONFIG_FOO and its define is
surrounded by #ifdef ... #endif, like follows:
#ifdef CONFIG_BAR
# define CONFIG_FOO
#endif
The header cleanup will leave empty #ifdef ... #endif:
#ifdef CONFIG_BAR
#endif
Likewise, if a define line between two blank lines
<blank line>
#define CONFIG_FOO
<blank lines.
... is deleted, the result of the clean-up will be successive empty
lines, which is a coding-style violation.
It is tedious to remove left-over garbage lines manually, so I want
the tool to take care of this. The tool's job is still not perfect,
so we should check the output of the tool, but I hope our life will
be much easier with this patch.

The current code for setting up the toolchain config always writes the new
paths to an item called 'toolchain'. This means that it will overwrite any
existing toolchain item with the same name. In practice, this means that:
buildman --fetch-arch all
will fetch all toolchains, but only the path of the final one will be added
to the config. This normally works out OK, since most toolchains are the
same version (e.g. gcc 4.9) and will be found on the same path. But it is
not correct and toolchains for archs which don't use the same version will
not function as expected.
Adjust the code to use a complete glob of the toolchain path.
