Image 'simple-bin' is missing external blobs and is non-functional: rockchip-tpl

/binman/simple-bin/mkimage/rockchip-tpl (../rkbin/bin/rk35/rk3588_ddr_lp4_2112MHz_lp5_2400MHz_v1.18.bin):
   An external TPL is required to initialize DRAM. Get the external TPL
   binary and build with ROCKCHIP_TPL=/path/to/ddr.bin. One possible source
   for the external TPL binary is https://github.com/rockchip-linux/rkbin.

/binman/simple-bin/fit/images/@tee-SEQ/tee-os (tee-os):
   See the documentation for your board. You may need to build Open Portable
   Trusted Execution Environment (OP-TEE) and build with TEE=/path/to/tee.bin
