[PATCH 6/9] ddr: Migrate DDR_SPD to Kconfig

Tom Rini
2021-08-21T17:51:24Z

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.
