Stefano,

    MX5: Update to autogenerated asm-offsets.h

    On i.MX5, the asm-offsets.h file is not yet generated as it should be.

building with O= does not work for me:

You are right. This is mainly due to the new targets in rules.mk, commit
f456445f29d22bb31ad29fdf1d6b2769decd37a2:

+$(TOPDIR)/include/asm/arch/asm-offsets.h:
$(TOPDIR)/include/autoconf.mk.dep \
+	$(TOPDIR)/$(CPUDIR)/$(SOC)/asm-offsets.s
+	@echo Generating $@
+	$(TOPDIR)/tools/scripts/make-asm-offsets
$(TOPDIR)/$(CPUDIR)/$(SOC)/asm-offsets.s $@

I have a fix, but I discovered that I have to generate the asm-offsets.h
as first target, exactly as it is currently done for
generic-asm-offsets.h. I have a patch, and I will send soon. I am not
very happy with it, because to fix dependencies I always generate a
asm-offsets.h, even for boards that do not need it. Maybe someone can
show me a more elegant way to do the same thing ;-)

Best regards,
Stefano
