IFC-NOR and QSPI-NOR pins are muxed on SoC,so they cannot be accessed simultaneously, but IFC-NOR can be accessed along with SD-BOOT.
ls1088aqds_sdcard_ifc_defconfig: is defconfig for SD as boot source and IFC-NOR to be used as flash, this will be used to write IFC-NOR image on IFC flash. QSPI and DSPI cannot be accessed in this defconfig.
IFC-NOR image is generated by ls1088aqds_defconfig.

More accurate timing are used which where provided by validation team
to switch to IFC-NOR use command for qspi prompt: i2c mw 66 0x60 0x12; i2c mw 66 50 00;i2c mw 66 10 21
Can you expand qixis command to do this? You should stop using i2c command to switch any banks.
Will that be ok to send separate patch with expansion of qixis commands ?
Yes, a patch before this one. I prefer not to use i2c command at all for bank switching. If you have any comment/document showing i2c command to do similar thing, please also clean up.
Please add instructions to board README file to describe the flash map, and the qixis commands to switch between QSPI banks, and other booting sources.
Flash map is now identical for all arm64 platform(ls2088,ls2085,ls1043,ls1046 and ls1088), do I still to add the flash map?
No, if identical. But please add the base addresses information.
