Priyanka,
I understand you don't have access to CPLD. Do you still have access to IFC NOR
flash? Can you boot from NOR flash, and issue a cpld command to reboot from
QSPI?

No, NOR and QSPI are muxed at RCW level. So, IFC is disabled for QSPI-boot.
We use QSPI emulator on board or code-warrior to write to on-board QSPI flash.
Also, for LS2088ARDB, we only have single QSPI flash. So no alternate bank.
What if the user brick the board by trashing QSPI flash? Is JTAG tool
the only way to recover? Can QSPI be accessed by booting from other sources?
The single bank QSPI will be a disaster if we cannot recover a bricked
board.
