$ openssl rc4 -provider legacy -K 7c4e0304550509072d2c7b38170d1711 \
	< mkimage-in-simple-bin.mkimage-u-boot-tpl | rkflashtool l
$ openssl rc4 -provider legacy -K 7c4e0304550509072d2c7b38170d1711 \
	< mkimage-in-simple-bin.mkimage-u-boot-spl | rkflashtool L

1b. Download the TPL and SPL using rkusbboot

$ rkusbboot \
	mkimage-in-simple-bin.mkimage-u-boot-tpl \
