"DSP is no use in current Buildroot" is not correct. The option exists,
and it changes the BR2_GCC_TARGET_CPU value. So it *is* used: it adds
"e" to BR2_GCC_TARGET_CPU. So this explanation is not really
good/sufficient.

I am willing to help you formulate this properly, but since I still
don't understand why you are dropping the DSP option, I can't really
help by proposing a better wording.

Best regards,

Thomas
