Thanks, but if we're going to do this, then can you please rename
CLK_FULL_SPEED to SYS_CLK_FREQ, as that is already defined in

./Kconfig

Change the "depends on ARC" in .Kconfig to "depends on ARC || ARCH_SUNXI",
and add an entry for it to board/sunxi/Kconfig only setting a default,
like we do for SYS_CONFIG_NAME / SYS_BOARD / SYS_SOC already

Regards,

Hans
