Add support for Sipeed's Lichee Pi 4A board which based on T-HEAD's TH1520 SoC, only minimal device tree and serial onsole are enabled, so it's capable of chain booting from T-HEAD's vendor u-boot.

No, here should be 'thead', since the CONFIG_SYS_VENDOR will form board/${CONFIG_SYS_VENDOR}, please consult arch/Kconfig for reference.
I personally would prefer 't-head' which probably cause less confusion.. but since kernel use 'thead'[1], so I just follow it to keep them aligned.
But you have a typo here :)
[1] in kernel, the dts path consist of 'thead', e.g. arch/riscv/boot/dts/thead/
