J721EXSOMXEVM: OSPI boot on SDK 7.1

Satish,

Your understanding is correct. The OSPI boot from SPL was descoped from the SDK 7.1.

We are doing some quick assessment of the current status on the SDK 7.1 and determine if there is an easy path to get you enabled on this. Will get back to you in a day or two.

Hi Satish,

The OSPI boot was working on the following commit ID. 

commit f2cd62a77d9b85005ff5a60e3839992ace0494b8 (tag: 07.01.00.001)

    configs: j7200_evm_a72: Update default mtdparts for 47040000.spi.0

    The MTD partitions listed are not what should be. Changes made are:

    - Move ospi.env.backup to 0x6C0000 so it does not lie in the middle of
      an erase block.

    - Make ospi.env and ospi.env.backup 256k so they span a full erase
      block.

    - Drop the sysfw partition. It is bundled with R5 SPL now.

    - Add the PHY calibration pattern partition.

    NOTE: The code in the OSPI driver is very naive so it won't actually
    read this variable to find the PHY pattern location as of now, and needs
    the partition to also be present in device tree. But this change will
    make sure Linux does not over-write the pattern thinking it is part of
    the rootfs.

Please use that attached sysfw.itb along with it.

We have validated this to be functional and therefore you can apply the patch that was provided offline to enable your flash.
