I haven't been able to find a document describing the ZSP G2 instruction set. Also the ARM7EJC in the rk2705 remains a mystery, assuming it's not a typo and ARM7EJ-S was meant instead.

In RealFunctions.c there's two references to zsp500
Code:
//ClrRegBit32(0x1801C000 + 0x1c, 5); //reset zsp500P
SetRegBit32(0x1801C000 + 0x1c, 4); //reset zsp500
