> (tag: v5.1.12)") introduced the parts of Linux Common Clock
> Framework, it was done for i.MX6 only and even had "depends on
> SPL_CLK_IMX6Q" conditions. Since commit
> ccab06689aa2 ("clk: imx: expose CCF entry for all") the framework can
> be re-used with SoCs of other vendors (say, TI), but NXP SoC-specific
> code is still being build. Is is especially problematic for size-constrained

Typo: Is->It

> SPL images on TI AM62x.
> 
> Make the build of the i.MX/RTxxxx code not only dependent on
> CONFIG_$(PHASE_)CLK_CCF, but also on CONFIG_MACH_IMX options
> which shall cover the i.MX platform users.
> 
> This saves 2264 bytes on 32-bit ARM platforms [using CCF].
