The firmware binary has to be loaded from lmem and the recommendation is to put all other objects in there as well. Note that we don't fall back to system memory if the allocation in lmem fails because all objects are allocated during driver load and if we have issues with lmem at that point something is seriously wrong with the system, so no point in trying to handle it.
