The reasion why we need to choise 22.03 branch is because openwrt-22.03 use the same kernel version linux-5.10 with RZ/G2L VLP3.0.x yocto sdk, so we can reduce the hard difficulty when portting renesas's smarc board driver to the kernel.

openwrt22.03 base on kernel version 5.10.116

openwrt21.02 base on kernel version 5.4.194

openwrt19.07 base on kernel version 4.14.275

openwrt18.06 base on kernel version 4.14.206
