So declaration should be in #ifndef too. Well ... I didn't object to that. I was just pointing out you're fixing forward declaration to undefined function. You should make a separate patch for that and explain it in the changelog so it's easily bisectable. > > > > static const struct gpio_bank gpio_bank_34xx[6] = { > > > > > > { (void *)OMAP34XX_GPIO1_BASE, METHOD_GPIO_24XX }, > > > > > > @@ -370,6 +373,7 @@ static void omap3_update_aux_cr_secure(u32 > > > set_bits, u32 clear_bits) } > > > > > > } > > > > > > +#ifndef CONFIG_SYS_L2CACHE_OFF > > > > > > static void omap3_update_aux_cr(u32 set_bits, u32 clear_bits) > > > { > > > > > > u32 acr; > > > > > > @@ -382,6 +386,7 @@ static void omap3_update_aux_cr(u32 set_bits, u32 > > > clear_bits) /* Write ACR - affects non-secure banked bits */ > > > > > > asm volatile ("mcr p15, 0, %0, c1, c0, 1" : : "r" (acr)); > > > > > > } > > > > > > +#endif > > > > Just move this function a few lines below instead of adding more CPP > > bloat. > > Function omap3_update_aux_cr is called only when CONFIG_SYS_L2CACHE_OFF is > not defined, so adding #ifndef is needed.

So declaration should be in #ifndef too. Right, but if we move the function to be just before it's used, inside the existing ifndef block we can remove the prototype instead.

Yep, it's just an function ordering issue being solved here. M
