QSPI0 and QSPI1 kernel bus driver for RZ/A2M

Hi team,

       We are working on RZ/A2M custom board which is having the two NOR flashes(MX25L51245G) connected to QSPI0 and QSPI1. our plan is to use the one flash as boot purpose an other one as data-storage purpose. while trying to integrate second flash QSPI1 in kernel stage, there is no node related to QSPI1(bus driver) in devicetree. Can you please help us to integrate the second nor flash from linux.

Kernel Version: 4.19

Thanks & Regards
