Questions about QSPI in LS1021A

Hi,

 

I am trying to use QSPI channel B on our LS1021A board, but I get confused :

1) In RM 30.1 QSPI signals, there are 2 QSPI channels in LS1021A.

2) In RM 4.4.5 RCW definition, there are no options for QSPI_DIO_B[0:2] in IFC_GRP_D_BASE/IFC_GRP_D_EXT.

So, can I use QSPI channel B or not? How should I set it up in RCW?

How should I configure it in linux kernel device tree?

 

Thanks
