You can turn all the 'bool, default y' into 'def_bool y'

Do you need it? If you always pass the timer frequency in the
device tree, you can skip the calibrate_delay portion of the boot
process and at the same time get a more accurate time representation.

Many architectures don't need this any more. Are you sure you still do?

This seems pointless as long as there is only a single one. If you don't
plan to add a second one in the near future, just leave the menu out.

Why set CONFIG_EMBEDDED? I don't see any options depending on that being
set.

Setting PREEMPT in the defconfig is fairly unusual.
