Applying the first two patches of this series into omap-for-v3.11/gpmc. Not taking the MTD patch, if it has dependencies to the first two patches please let me know and also get an ack from Artem if you want me to take it.

Oops, dropping the second patch in this series as it causes the following if only omap4 is selected for example: arch/arm/mach-omap2/built-in.o: In function `gpmc_resume': dss-common.c:(.text+0x9a8): undefined reference to `omap3_gpmc_restore_context' arch/arm/mach-omap2/built-in.o: In function `gpmc_suspend': dss-common.c:(.text+0x9c8): undefined reference to `omap3_gpmc_save_context' Can you please take a lok and fix that?
