For some newer SoCs like RK3568, the Rockchip has not released any DDR drivers yet so idbloader needs to create manually using DDR binaries offered by rkbin. This indeed no requirement to enable TPL in the U-Boot source code.
If we mark TPL disabled and mark BINMAN enabled by default then there would be an issue of binman_init failure during board relocation. This is true as binman failed to find the top-level node like u-boot-tpl here.
Here is the boot issue observed in RK3566 board,
U-Boot 2023.01-rc4-00057-gac2505d463-dirty (Jan 04 2023 - 23:44:18 +0530)
Model: Radxa Compute Module 3(CM3) IO Board DRAM: 2 GiB binman_init failed:-2 initcall sequence 000000007ffd2008 failed at call 0000000000a18cac (err=-2) ### ERROR ### Please RESET the board ###
This might be fixed via binman node in rockchip-u-boot.dtsi however disable binman for rk3568 for now as we are at the end of the release cycle.
