Read a 32-bit microcode data value from a text file and convert to raw binary form.
Arguments:
InFptr - file pointer to input text file
Data - pointer to where to return the data parsed
Returns:
STATUS_SUCCESS - no errors or warnings, Data contains valid information
STATUS_ERROR - errors were encountered
