I don't know of any u-boot supoort for iscsi, but its always possible. I expect that aarch64 from day 1 will support iSCSI. I think that the 32 bit devices that have UEFI should have support also. I wasn't referring to iSCSI via uboot, there's other means of achieving it. Right and that was clear in your email, I was filling in some missing details from your email. as there is multiple ways for an iscsi target to be enumerated and your answer only partially answered the question.
