6516c9b349 spl: binman: Disable u_boot_any symbols for i.MX8M boards
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.

d8830cf840 spl: binman: Split binman symbols support from enabling binman
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).

e09a8b9f1b spl: binman: Make TPL_BINMAN_SYMBOLS depend on TPL_FRAMEWORK
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.

ba787bb458 spl: Move all VPL, TPL and PowerPC specific CONFIG options to separate files
- Move all PowerPC (and some shared with Layerscape) options to
  common/spl/Kconfig.nxp
- Move all other TPL related options to common/spl/Kconfig.tpl
- Move all VPL related options to common/spl/Kconfig.vpl

This makes the whole of common/spl/Kconfig slightly more readable.
