Quad Enable Bit

 

Spansion S256

 

Checking if the Quad Enable bit is set is possible from u-boot 

> sspi 0 16 35

if result is 0002 then the nonvolatile Quad Enable bit is set

It is also possible to write the Quad Enable bit, 2 commands are needed

 

> sspi 0 8 06

> sspi 0 24 010002

The above will set Quad Enable bit in non volatile status register
