This breaks the build when CONFIG_OF is defined but not CONFIG_DDR: drivers/built-in.o: In function `of_get_ddr_timings': drivers/memory/of_memory.c:138: undefined reference to `lpddr2_jedec_timings' drivers/built-in.o: In function `of_get_min_tck': drivers/memory/of_memory.c:62: undefined reference to `lpddr2_jedec_min_tck' make: *** [vmlinux] Error 1 To solve this, only compile of_memory.c when CONFIG_OF && CONFIG_DDR, otherwise, stub out the functions.

LPDDR2 generic timings extraction from device is managed using couple of helper functions which can be used by other memory controller drivers.
