Subject: [RESEND PATCH 1/2] memory: move jedec_ddr_data.c from lib/ to drivers/memory/
Date:   Mon,  3 Jun 2019 17:12:32 +0900
Message-Id: <20190603081233.17394-2-yamada.masahiro@socionext.com>
In-Reply-To: <20190603081233.17394-1-yamada.masahiro@socionext.com>
References: <20190603081233.17394-1-yamada.masahiro@socionext.com>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

jedec_ddr_data.c exports 3 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.
