[U-Boot] [PATCH 2/2][v5] nxp/ls2080ardb: Add QSPI-boot support

QSPI-boot is verified on LS2088ARDB RevF board with LS2088A SoC. LS2088ARDB RevF Board has limitation that QIXIS can not be access, so QIXIS flag is kept disabled
Signed-off-by: Priyanka Jain priyanka.jain@nxp.com Signed-off-by: Suresh Gupta suresh.gupta@nxp.com --- Changes for v5: Renamed defconfig to ls2088ardb_qspi_defconfig and incorporated other review comments
Changes for v4: Updated copyright Changes for v3: Updated README
Changes for v2: Incorporated Sun York's comments Introduced another patch to update qixis related code

Priyanka,
Do not tab in subject.
I thought about it again. Even LS2088A is the only SoC on this board, it is still possible to put a different SoC on it. We have come a long way to unify the configuration name, let's stick with LS2080ARDB. It's OK to mention LS2088ARDB rev F in commit message, and/or README file. Sorry for previous misleading comment.
When you add a new defconfig, please update MAINTAINERS file.

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?
York
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.

QSPI can be accessed also by attaching QSPI emulator device on boards. This issue has been resolved in another similar platform LS2081ARDB which has dual QSPI flash. Priyanka

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?
York
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?

Let's say a customer has this board without QSPI emulator, or CW Tap, is there any way to program QSPI flash if it is bricked?
You have another patch to enable SD for this board. Can this board boot from SD and access QSPI?
