In particular, it does not prevent a configuration with 'DRM_CMA=m'
I assume you meant "DRM_CMA=n" ? DRM_CMA cannot be built as a module.
Ok, at least that makes it easier.
and 'DRMA_ASPEED_GFX=y', or any build failures from such
a configuration.
I don't follow. "DRM_CMA=n" and

Random drivers should not override a user configuration of core knobs
(e.g., CONFIG_DMA_CMA=n). Use "imply" instead, to still respect
dependencies and manual overrides.
"This is similar to "select" as it enforces a lower limit on another
symbol except that the "implied" symbol's value may still
