[U-Boot] [PATCH 0/8] Initial integration of AVB2.0

Hi Igor,

    It's great to see the patch set to support AVB2.0, the upstream
libavb(from aosp) combine the AVB with A/B which I think should be
two separate feature, are you going to split them?

    BTW, do you have plan to update boot_android cmd to support avb?
the command is too weak for use now.
And any plan to add opptee_client/smcc to talk to OPTEE/ATF?

Thanks,
- Kever
