The i.MX8M boards use partially specified binman images which have an
SPL entry without a U-Boot entry. This would normally cause an error due
to the 'u_boot_any' binman symbols declared by BINMAN_UBOOT_SYMBOLS
requiring a U-Boot-like entry in the same image as the SPL.
However, a problem in the ARMv8 __image_copy_start symbol definition
effectively disables binman from attempting to write any symbols at all,
so everything appears to work fine until runtime. A future patch fixes
the issue in the linker scripts, which lets binman fill in the symbols,
which would result in the build error described above.
Explicitly disable the 'u_boot_any' symbols for i.MX8M boards. They are
already effectively unusable, and they are incompatible with the boards'
current binman image descriptions.

Binman lets us declare symbols in SPL/TPL that refer to other entries in
the same binman image as them. These symbols are filled in with the
correct values while binman assembles the images, but this is done
in-memory only. Symbols marked as optional can be filled with
BINMAN_SYM_MISSING as an error value if their referred entry is missing.
However, the unmodified SPL/TPL binaries are still available on disk,
and can be used by people. For these files, nothing ensures that the
symbols are set to this error value, and they will be considered valid
when they are not.
Empirically, all symbols show up as zero in a sandbox_vpl build when we
run e.g. tpl/u-boot-tpl directly. On the other hand, zero is a perfectly
fine value for a binman-written symbol, so we cannot say the symbols
have wrong values based on that.
Declare a magic symbol that binman always fills in with a fixed value.
Check this value as an indicator that symbols were filled in correctly.
Return the error value for all symbols when this magic symbol has the
wrong value.
For binman tests, we need to make room for the new symbol in the mocked
SPL/TPL data by extending them by four bytes. This messes up some test
image layouts. Fix the affected values, and check the magic symbol
wherever it makes sense.

The SPL code declares binman symbols for U-Boot phases depending on
CONFIG_IS_ENABLED(BINMAN_UBOOT_SYMBOLS). This config exists for SPL and

Enabling CONFIG_BINMAN makes binman run after a build to package any
images specified in the device-tree. It also enables a mechanism for
SPL/TPL to declare and use special linker symbols that refer to other
entries in the same binman image. A similar feature that gets this info
from the device-tree exists for U-Boot proper, but it is gated behind a
CONFIG_BINMAN_FDT unlike the symbols.
Confusingly, CONFIG_SPL/TPL_BINMAN_SYMBOLS also exist. These configs
don't actually enable/disable the symbols mechanism as one would expect,
but declare some symbols for U-Boot using this mechanism.
Reuse the BINMAN_SYMBOLS configs to make them toggle the symbols
mechanism, and declare symbols for the U-Boot phases in a dependent
BINMAN_UBOOT_SYMBOLS config. Extend it to cover symbols of all phases.
Update the config prompt and help message to make it clearer about this.
Fix binman test binaries to work with CONFIG_IS_ENABLED(BINMAN_SYMBOLS).

TPL_BINMAN_SYMBOLS depends on SPL_FRAMEWORK. The code this enables is
compiled by checking CONFIG_$(SPL_TPL_)FRAMEWORK, so it should depend on
TPL_FRAMEWORK instead (which in turn depends on SPL_FRAMEWORK). This was
most likely a typo due to copy-pasting the config's SPL version, fix it.
Signed-off-by: Alper Nebi Yasak <alpernebiyasak@gmail.com>
Some SPL functions directly use the binman 'u_boot_any' symbols to get
U-Boot's binman image position. These symbols are declared by the
SPL/TPL_BINMAN_SYMBOLS configs, but they are accessed by macros defined
by just CONFIG_BINMAN. So when BINMAN is enabled and BINMAN_SYMBOLS is
disabled, the code tries to use undeclared symbols and we get an error.
Therefore, any use of 'u_boot_any' symbols in the code is an implicit
dependency on SPL/TPL_BINMAN_SYMBOLS. However, in the current uses
they are meant to be the next phase's values, where that happens to be
U-Boot. In the meantime, helper funcions spl_get_image_pos/size() were
introduced to get these values.
Convert all uses of u_boot_any symbols to these functions, so we only
access these symbols at one place. Make sure they will not use these
symbols when the BINMAN_SYMBOLS configs are disabled, by returning early
in those cases.

At present tag numbers are only allocated for non-core data, meaning that

For debugging and consistency it is convenient to use tags for this 'core'

While running tests for a python tool, the tests' outputs get printed in
whatever order they happen to run, without any indication as to which
output belongs to which test. Unittest supports capturing these outputs
and printing them as part of the test summaries, but when a failure or
error occurs it switches back to printing as the tests run. Testtools
and subunit tests can do the same as their parts inherit from unittest,
but they don't outright expose this functionality.
On the unittest side, enable output buffering for the custom test result
class. Try to avoid ugly outputs by not printing stdout/stderr before
the test summary for low verbosity levels and for successful tests.
On the subunit side, implement a custom TestProtocolClient that enables
the same underlying functionality and injects the captured streams as
additional test details. This causes them to be merged into their test's
error traceback message, which is later rebuilt into an exception and
passed to our unittest report class.

The python tools' test utilities handle printing test results, but the
output is quite bare compared to an ordinary unittest run. Delegate
printing the results to a unittest text runner, which gives us niceties
like clear separation between each test's result and how long it took to
run the test suite.
Unfortunately it does not print info for skipped tests by default, but
this can be handled later by a custom test result subclass. It also does
not print the tool name; manually print a heading that includes the
toolname so that the outputs of each tool's tests are distinguishable in
the CI output.

It's possible to request a specific test to run when trying to run a
python tool's tests. If we request a nonexistent test, the unittest
loaders generate a fake test that reports this as an error. However, we
get these fake tests even when the test exists, because test_util can
load tests from multiple places one by one and the test we want only
exists in one.
The test_util helpers currently remove these fake tests when printing
test results, but that's more of a workaround than a proper solution.
Instead, don't even try to load the missing tests.
