[PATCH v4 0/2] memory: Introduce ti-emif-sram driver

[Dave Gerlach]

Hi,
This is v4 of the series introduces a ti-emif-sram driver to be used on
am335x and am437x, based on v4.14-rc1. This version addresses some
comments from Russell King and Johan Hovold in v3 found here [1].

The main change in this version is dropping the additions to the
arch/arm/kernel/asm-offsets.c file and instead generating our own local
"emif-asm-offsets.h" using the same strategy in the drivers/memory Makefile.
This keeps our driver changes out of the arch or platform code and is a
cleaner implementation. Otherwise some small fixups based on comments from
Johan in v3 were done.

This code is required for low-power modes to work on AM335x and AM437x and a
forthcoming PM series for those platforms will depend on this series. After
both this and the PM series are reviewed I will send the necessary device tree
changes for both, but in the meantime all remaining patches for am335x and
am437x PM can be found here [2].

Regards,
Dave
