At present U-Boot environment variables, and thus scripts, are defined
by CONFIG_EXTRA_ENV_SETTINGS. It is painful to add large amounts of text
to this file and dealing with quoting and newlines is harder than it
should be. It would be better if we could just type the script into a
text file and have it included by U-Boot.
Add a feature that brings in a .env file associated with the board
config, if present. To use it, create a file in a board/<vendor>
directory, typically called <board>.env and controlled by the
CONFIG_ENV_SOURCE_FILE option.
The environment variables should be of the form "var=value". Values can
extend to multiple lines. See the README under 'Environment Variables:'
for more information and an example.
In many cases environment variables need access to the U-Boot CONFIG
variables to select different options. Enable this so that the environment
scripts can be as useful as the ones currently in the board config files.
This uses the C preprocessor, means that comments can be included in the
environment using /* ... */
Also support += to allow variables to be appended to. This is needed when
using the preprocessor.

Quite a lot of the code in common/relates to booting and images. Before
adding more it seems like a good time to move the code into its own
directory.
Most files with 'boot' or 'image' in them are moved, except:
- autoboot.c which relates to U-Boot automatically running a script
- bootstage.c which relates to U-Boot timing
Drop the removal of boot* files from the output directory, since this
interfers with the symlinks created by tools and there does not appear
to be any such file from my brief testing.

When linking the final u-boot binary with LLD, the following link errors
are seen:

According to Nick Desaulniers:
"This is a known difference between GNU and LLVM linkers; the GNU
linkers permit relocations in readonly segments (making them not read
only), LLVM does not (by default)."
Since U-Boot apparently seems to use relocations in readonly segments,
change the global linker flags to permit them when linking with LLD by
specifying '-z notext'.

So let's replace that with the existing OF_BOARD. U-Boot would then

At present U-Boot always builds dtc if CONFIG_OF_CONTROL is defined, even
when DTC is provided. The built dtc is not actually used, so this is a
waste of time.
Update the Makefile logic to build dtc only if one is not provided to the

Since derivatives are moving to binman from usage of the FIT generator
script, and considering the warning introduced in f4a43d2925
("Makefile: Warn against using CONFIG_SPL_FIT_GENERATOR"), usage of FIT
generator is discouraged.
Current FIT generator also generates broken output, since commit
3f04db891a ("image: Check for unit addresses in FITs") prohibits using
'@' for unit addresses but the generator script still emits the old
sematics.
Remove the generator script and corresponding call in Makefile, all
derivatives should be migrated to binman in order to provide binary

The data part of v1 kwbimage currently contains U-Boot binary prepended
by 64 bytes long Legacy U-Boot image header. This means that the load
address is currently substracted by 64 bytes to ensure that U-Boot's
entry point is at specified execution address.
As mkimage has already separate arguments for load (-a) and execution
(-e) address, there is no need to derive fixed load address from
execution address.
Therefore remove this load address hack from the kwbimage tool and
support generating v1 kwbimage with arbitrary addresses for load and
execution.
Finally, calculate correct load address by caller for mkimage tool in
Makefile. File u-boot-spl.kwb is always a v1 kwbimage and it is the only
v1 kwbimage which U-Boot's build system generates.

BIOS Release Date must be in format mm/dd/yyyy and must be release date.
U-Boot currently sets BIOS Release Date from U_BOOT_DMI_DATE macro which is

Fix this issue by setting U_BOOT_DMI_DATE macro to U-Boot version which is
better approximation of U-Boot release date than current build timestamp.
Current U-Boot versioning is in format yyyy.mm so as a day choose 01.
Some operating systems are using BIOS Release Date for detecting when was
SMBIOS table filled or if it could support some feature (e.g. BIOS from
1990 cannot support features invented in 2000). So this change also ensures
that recompiling U-Boot from same sources but in different year does not

- Remove other parts of Kconfig logic that had platforms pick DM_USB.
- To keep Kconfig happy, have some select statements test for USB_HOST

- Re-order some Kconfig entries and menus so that we can cleanly pick
host or gadget roles. For the various HCD options that have platform
