- BR2_PACKAGE_IVI_HOMESCREEN_AUDIO_PLAYERS selects gstreamer1, which
has a depends on BR2_USE_MMU, but does not propagate it
- BR2_PACKAGE_IVI_HOMESCREEN_FLUTTER_SECURE_STORAGE_PLUGIN selects
libsecret, which has a depends on BR2_USE_MMU, but does not propagate
it
In practice there is no problem since ivi-homescreen depends on glibc,
and glibc doesn't support any noMMU architecture. But just by walking
the chain of option dependencies, this is not something that is
theoretically guaranteed (making automated verification of
dependencies difficult).
The other "depends on" from gstreamer1 and libsecret, BR2_USE_WCHAR
and BR2_TOOLCHAIN_HAS_THREADS are on the other hand already handled by
the top-level BR2_PACKAGE_IVI_HOMESCREEN option, so there is no
ambiguity.
