![]() TPL builds today don't need to call into firmware or set up the MMU (if this changes, it should be controlled through a config option whether to include this or not), but include the needed support code for this anyway. By moving these unused low-level functions into seperate function-sections, the linker can garbage-collect the unused sections. Note that (if DM support is enabled), there will be a call to the cache-flushing code from alloc_priv(...) in drivers/core/device.c. This then add 52 bytes of binary size (an increase from 20589 to 20641 bytes) compared to completely removing this code. Even for a feature-rich TPL (including DM support as for the RK3368), this equates to a size difference of significantly more than 10% in TPL binary size.
