> Commit d941f86fad41b ("ARM: l2c: AM43x: add L2 cache support") enabled
> the L2 cache support for the am43xx SoC, but caused a build regression
> when the driver for that cache controller is disabled:
>
> arch/arm/mach-omap2/built-in.o: In function `am43xx_init_early':
> :(.init.text+0xb20): undefined reference to `omap_l2_cache_init'
>
> This did not happen for OMAP4, which has the same call, but enables
> the l2x0 driver unconditionally. We could do the same thing for
> am43xx, but it seems better to allow turning it off and make the
> code work in either case.
>
> This adds an inline wrapper for omap_l2_cache_init for the disabled
> case, and removes the 'select' from OMAP4 so it becomes a user
> visible option.
