I think the CPU core in this chip is the Chinese CSky design, but there are many versions of this core.
GCC now supports some CSky processors, but possibly does not support the processor core used in the C7000
HR-C7000 is a SOC solution that integrates C-SKY CK803S MCU inside of it, C-SKY is now a legacy product of Alibaba's sub-company called T-Head, they are more focused on RISC-V products now.
CK803S is supported by gcc for specifing "-march=ck803 -mcpu=ck803s" refer to https://gcc.gnu.org/onlinedocs/gcc/C-SKY-Options.html
But maybe you need to build the toolchain by yourself refer to https://github.com/c-sky/toolchain-build
I am sorry that I don't know too much information about Ghidra C-SKY-related topics
