If CONFIG_OF is n, gcc fails:
drivers/memory/omap-gpmc.o: In function `gpmc_omap_onenand_set_timings':
omap-gpmc.c:(.text+0x2a88): undefined reference to `gpmc_read_settings_dt'
Add helper function to fix this.

Hi,
Instead add empty stub for gpmc_read_settings_dt() in existing #ifdef
section - around line 2314. Less ifdefs and actually seems to me
appropriate place to group !OF stubs.
Best regards,

I will suggest to set gpmc_settings data structure to zero here so that
the caller doesn't proceed with random/invalid settings.

If there is resend, please fix it as well.
