Hi, 

The initialization of SPI0 module pins and clock seems right. One problem can with the comparison in register_write()

if(SPI0_S == 0x20)‍‍‍‍‍

Instead of this comparison, try:

if((SPI0_S & 0x20) == 0x20)‍‍

(Because other bits in SPI0_S like SPRF, SPMF can also be 1. Then SPI0_S may not be 0x20 always)

Good luck
