Dumping TSOP48 flash
It would appear the S29GL032N does not have a (serial) SPI interface.  It is access using (parallel) address and data lines.  There appears to be 21 (A0 - A20) address lines available on the '32 version of the chip.  And 16 (DQ0 - DQ15) data lines.  This will be problematic for most Arduinos as most Arduinos do not have 37 GPIO lines.
