Jetson TK1 NOR-Flash

i tried to find out if the 4MB SPI boot flash is a NOR-Flash.
The only information i got, from the nvidia schematics, was the chip type used on the board. It should be a winbond W25Q32DW.
After a little bit of research, the used chip should be a serial-nor-flash.
Is that right? Does the Board use that winbond chip? And is that chip an NOR-Flash type?

It should be a serial-nor-flash

W25Q32DW datasheet doesn’t mention flash type though

Winbond site mention NOR flash lineup

It’s most likely to be NOR flash type
