This gives us support for the new -s (strict mode) and -Q (disable
warnings) options. The latter will be used in the follow-up commit.

We currently use scripts/kconfig/merge_config.sh only in MAKEALL.

QEmu's Malta emulation can be used in four flavors depending on
endianness and CPU register width. So far we only had two defconfigs and
expected users to adjust the config to arrive at the other two flavors
to cut down on duplication in the config files. Let's use the new merged
defconfigs mechani
We'll start using these fragments inside Kbuild too for merged defconfigs
to cut down on defconfigs that are largely duplicated, but differ only
in a few options. To share such configs between architectures, we add
common/boards/configs as a common fragment directory here and
standardize on using .
Build with no console whatsoever is not a common configuration for
development, but is used in some verified boot scenarios. Some
configurations go even further and disable the shell altogether.
Add headless.config and noshell.config fragments that describes these

The reboot_mode_add_globalvar initcall would run even without
CONFIG_GLOBALVAR if it didn't fail at link time, because it references
the global_device. Fix this by only registering the initcall if global
variable support is enabled.

While sandbox defines arch_ctrlc() unconditionally, ctrlc() is not
defined when CONFIG_CONSOLE_NONE=y for all architectures, so we need the
inline stub on sandbox too to avoid a link error.

Some common networking code like fastboot over UDP calls ifup_all(0) to
bring up all interfaces. ifup_all(0) in turn runs commands to execute
interface discovery scripts and source network configurations.
This leads to a link error, because run_command is not defined in a

Linux & BSD define the ioctl command parameter to be always unsigned.
POSIX differs and uses a signed integer instead, but as we are importing
Linux code, it makes sense to use the same signedness to avoid false
positive warnings about sign-extended constants that get truncated.

There's no point in compiling PBL decompression code when
CONFIG_HAVE_IMAGE_COMPRESSION is not selected, so reflect that in Kbuild
to save some build time.

of_unflatten_dtb allocates an unflattened tree and of_overlay_apply_tree
copies it into another tree. The unflattened tree is then usually
leaked. Add a function that takes care of these two steps and then frees
the tree.

The check for the magic values should thus ensure that at least 56 bytes
