	depends on BR2_arm

would probably be nice here.

No need to align this second line.

Remove double quotes.

Add:

	mv $(@D)/ti-cgt-pru_2.1.3/* $(@D)
	rmdir $(@D)/ti-cgt-pru_2.1.3/

I'd think I'd prefer:

TI_PRU_CGT = $(HOST_DIR)/usr/share/ti-cgt-pru/

We usually use 'mkdir -p' instead.

	cp -dpfr $(@D)/* $(TI_PRU_CGT)

Thanks!
