* This function prototype is only used by the AMD Dinar mainboard. The SMBus
* write is used to select which socket's SPD will be read by the subsequent
* SPD read call. This function is being placed in the F15 wrapper code with
* the other SPD read functions because the next step of the SPD read clean-up
* will be to move the SMBus read/write functions into the southbridge to make
* them more generic. Having the writeSmbusByte() function in the same file as
* the readSmbusByte() function will ensure that the writeSmbusByte() function
* is not overlooked.
