A solution that I see is to allow pm-asm-offsets to just include the macros that
would be defined by emif-asm-offsets in the header generated by pm-asm-offsets.
This way there is no need to introduce the arch -> drivers build dependency that
is causing our issue, each driver generates its own header with everything it
needs included. I'll move the actual macro definitions for emif-asm-offsets.c
into a header and then by including them in both emif-asm-offsets and
pm-asm-offsets we get all macro definitions in both places with them still being
defined only in one location.

I've inlined the changes below. I will send a proper split up series if it's
considered acceptable.

Regards,
Dave

Subject: [PATCH] RFC: Fix build when using split object directories

The sleep33xx and sleep43xx files should not depend on a header file
generated in drivers/memory. Remove this dependency and instead generate
the macros needed as part of pm-asm-offsets.c to avoid complicating the
build.

Seems fine from my point of view. No need to split the patch, best to
do the fix as a single patch.

We should test build it also with make randconfigs though.

So assuming others are OK with this and it does not introduce
new randconfig build errors:

Nit:
You are touching these two lines.
You can also describe it like this:

$(obj)/sleep33xx.o $(obj)/sleep43xx.o: include/generated/ti-pm-asm-offsets.h



I prefer putting the local header, ti-pm-asm-offsets.h,
into arch/arm/mach-omap2/, but that is a different issue.

So, I am fine with this.
