Subject: [PATCH 6/9] ddr: Migrate DDR_SPD to Kconfig
Date: Sat, 21 Aug 2021 13:50:16 -0400	[thread overview]
Message-ID: <20210821175019.24180-6-trini@konsulko.com> (raw)
In-Reply-To: <20210821175019.24180-1-trini@konsulko.com>

Move the symbol that controls building some JEDEC SPD support functions
to Kconfig.  This is required on the TI keystone 2 platforms and very
frequently (but not always) used on large number of Freescale/NXP
platforms, so use imply there.
