Hi, This is v5 of the series introduces a ti-emif-sram driver to be used on am335x and am437x. The previous version of this series can be found here [1]. The only change to this version is to greatly simplify the makefile rules used to generate the emif-asm-offsets header to fix some build issues caught by the kbuild robot. The file has been renamed as ti-emif-asm-offsets.h and is also now placed under include/generated so that it is handled along with the other generated headers. The macros were left inside the "ti_emif_offsets" inline function in the ti-emif-sram header as they are also needed by the sleep33xx and sleep43xx from the "code (seen here [2]), and describing the build depency on the generated ti-emif-asm-offsets.h file got messy. Just including the macros in the asm-offsets file generated for the arch/arm/mach-omap2 was the cleanest way I could come up with, otherwise ensuring that ti-emif-asm-offsets.h is generated before sleep33/43xx.S gets built was problematic. Of course, I am open to a better idea if someone has one. 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 [3].
