Subject: spdx-common: Add documentation for undocumented SPDX variables
X-Git-Tag: yocto-6.0_M3~301
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=fa10e1b59b2068e14bb37ddcc9913ca8d23b15a8;p=thirdparty%2Fopenembedded%2Fopenembedded-core.git

spdx-common: Add documentation for undocumented SPDX variables

Add [doc] strings for eight undocumented SPDX-related BitBake
variables in spdx-common.bbclass.

Variables documented:
- SPDX_INCLUDE_SOURCES
- SPDX_INCLUDE_COMPILED_SOURCES
- SPDX_UUID_NAMESPACE
- SPDX_NAMESPACE_PREFIX
- SPDX_PRETTY
- SPDX_LICENSES
- SPDX_CUSTOM_ANNOTATION_VARS
- SPDX_MULTILIB_SSTATE_ARCHS

This makes variables discoverable via bitbake-getvar and IDE
completion, improving usability for SBOM generation.
