In the mean time could linker sets be used in drivers or BSPs to declare
a table of "resources" they need and these are added to the confdefs.h
defined values during initialisation?
Yes, this would probably work. You should however compare the complexity of
1) linker sets
+ dynamic workspace size changes
+ static pre-processor based workspace size estimate (just look at
the pre-processed output of confdefs.h)
+ workspace (heap)
+ objects
+ side-effects, e.g. subsystem which doesn't account for its resources
+ initialization order
+ run-time initialization errors
vs.
2) provide some storage (16 bytes for a mutex on a 32-bit target)
+ initialize the object (= initialize storage to zero, no possible
errors, may reside in .bss)
