The test for (CONFIG_BOOTDELAY >= 0) has been in U-Boot since the
beginning, but the meaning of it has changed over time. Allow the
default to be set for any value, including -ve ones. This allows
(for example) CONFIG_ENV_IS_NOWHERE to have values for bootdelay in
its compiled in environment.
The only thing this changes is where the default for bootdelay can be
fetched from; before this change you get a compiled in default, after
you'll pull it from the default value in the environment, but both values
will be the same. Also if there's a value set in the environment then
that will take precedence (as before).

When U-Boot started using SPDX tags we were among the early adopters and
there weren't a lot of other examples to borrow from. So we picked the
area of the file that usually had a full license text and replaced it
with an appropriate SPDX-License-Identifier: entry. Since then, the
Linux Kernel has adopted SPDX tags and they place it as the very first
line in a file (except where shebangs are used, then it's second line)
and with slightly different comment styles than us.
In part due to community overlap, in part due to better tag visibility
and in part for other minor reasons, switch over to that style.
This commit changes all instances where we have a single declared
license in the tag as both the before and after are identical in tag
contents. There's also a few places where I found we did not have a tag
and have introduced one.

CONFIG_HOSTNAME is defined as a "plain" preprocessor string, but every
use is couched by __stringify(...).
Hence, convert it to a proper string option.

Modifying the default environment via CONFIG_EXTRA_ENV_SETTINGS is
somewhat inflexible, partly because the cpp language does not allow
appending to an existing macro. This prevents reuse of "environment
fragments" for different boards, which in turn makes maintaining that
environment consistently tedious and error-prone.
This implements a Kconfig option for allowing one to define the entire
default environment in an external file, which can then, for example, be
generated programmatically as part of a Yocto recipe, or simply be kept
in version control separately from the U-boot repository.

Commit 7653942b10 ("common/env_embedded.c: drop support for
CONFIG_SYS_USE_PPCENV") dropped the .ppcenv section which was
used in linking scripts to allow fine placement of embedded
environment sections.
This implies that GCC randomly places objects from env/embedded.o
and environment is not guaranteed to be located at the correct address:
04003df8 g F .text 00000038 mii_init
04004000 g O .text 00000004 env_size
04004004 g O .text 00002000 environment
04006004 g F .text 00000040 .hidden __lshrdi3
This patch restores this capability by allocating each object marked
with __UBOOT_ENV_SECTION__ into a different section. Hence
'environment' will be alone in .text.environment, allowing a
fine placement in u-boot.lds with:
. = DEFINED(env_offset) ? env_offset : .;
env/embedded.o (.text.environment)

The environment has pretty much nothing to do with just "PPC", so
rename the macros to just __UBOOT_ENV_SECTION__ which is more
readable.
In addition, only a single macro is needed: the environment now goes
either to the default section (USE_HOSTCC is defined) or in the .text
section.

We really don't want boards defining fixed MAC addresses in their config
so we just remove the option to set it in a fixed way. If you must have
a MAC address that was not provisioned, then use the random MAC address
functionality.

Currently just validates variable types as decimal, hexidecimal,
boolean, ip address, and mac address.
If the entry is not found in the env ".flags", then look in the static
one. This allows the env to override the static definitions, but prevents
the need to have every definition in the environment distracting you.

!!!fix comment in callback
CONFIG_ENV_VARS_UBOOT_CONFIG creates environment variables indicating
which configuration U-Boot was built for. Some U-Boot binaries run on
multiple boards, and hence this information may not uniquley describe
the HW that U-Boot is actually running on. Another patch introduces
environment variable board_name to represent that. In order to avoid
scripts having to check $board_name, use it if set, and then fall back
to using $board, make CONFIG_ENV_VARS_UBOOT_CONFIG also set a default
value for board_name, so that variable is always available.

The env code is protected by the ENV_IS_EMBEDDED define, so attempting to
compile the code when this isn't defined is pointless. Now that the env
headers have unified around CONFIG_ENV_IS_EMBEDDED, convert the build
system to only build the env objects when this is enabled. And now that
the env code is conditionally compiled, we can drop the source code checks.
For people who want to extract the environment manually, add a new option
CONFIG_BUILD_ENVCRC that only enables the envcrc utility.

With recent toolchains, the environment sectors were no longer aligned to
sector boundaries. The reason was a combination of two bugs:
1) common/environment.c assumed that CONFIG_TQM8xxL would be defined
for all TQM8xxL and TQM8xxM boards. But "include/common.h", where
this gets defined, is not included here (and cannot be included
without causing lots of problems).
Added a new #define CFG_USE_PPCENV for all boards which really
want to put the environment is a ".ppcenv" section.
2) The linker scripts just include environment.o, silently assuming
that the objects in that file are really in the order in which
they are coded in the C file, i. e. "environment" first, then
"redundand_environment", and "env_size" last. However, current
toolchains (GCC-4.x) reorder the objects, causing the environment
data not to start on a flash sector boundary:
Instead of: we got:
40008000 T environment 40008000 T env_size
4000c000 T redundand_environment 40008004 T redundand_environment
40010000 T env_size 4000c004 T environment
Note: this patch fixes just the first part, and cures the alignment
problem by making sure that "env_size" gets placed correctly. However,
we still have a potential issue because primary and redundant
environment sectors are actually swapped, i. e. we have now:
40008000 T redundand_environment
4000c000 T environment
40010000 T env_size
This shall be fixed in the next version.
