[U-Boot] [PATCH] arm64: ls1043ardb: Add distro secure boot support
Enable validation of boot.scr script prior to its execution dependent on "secureboot" flag in environment. Disable fall back option to nor/qspi boot in case of secure boot. Also enable "secureboot=y" flag in environment for ARM based platforms instead of bootcmd.

Can you add the steps to board README or a general README file to describe the steps to make distro boot on these boards? I don't think it is common knowledge yet. Last time when I tried on LS2080ARDB, it took me quite some effort to sort it out.

As per my understanding DISTRO boot is common feature in u-boot and we have enabled it on our boards. Please refer to "doc/README.distro".

You are correct about the issue. Actually I have to send a patch upstream to enable fallback option in case of LS1043, LS1046 and LS1021. But if you see on LS2088 and LS1088, fallback option is already there in upstream.
