That certainly suggests a ZSP500, but it's still just a comment. I'm not convinced yet because there are discrepancies: the "ZSP500" in the rk2705 doesn't run at 400 MHz, but only at 176 MHz; furthermore it is said to have not a 24-bit, but a 32-bit address space.

A simple test is to check a driver using a ZSP200/ZSP400/ZSP410 disassembler and see if it skips instructions or produces errors. If it doesn't we're back to square one.

Actually I'm more interested in the question if the rk2705 has a MMU.
