[PATCH 1/2] memory: move jedec_ddr_data.c from lib/ to drivers/memory/

From: Masahiro Yamada
Date: Wed May 15 2019 - 11:06:18 EST


jedec_ddr_data.c exports the lpddr2_jedec_* symbols, and all of them
are only referenced from drivers/memory/{emif.c,of_memory.c}

drivers/memory/ is a better location than lib/.

I removed the Kconfig prompt "JEDEC DDR data" because it is only
select'ed by TI_EMIF, and there is no other user. There is no good
reason in making it a user-configurable CONFIG option.
