Ha, yes me to. Although having ATF output on UART3 and u-boot on UART0 is a
bit annoying.
If your going to continue using UART0, I would also recommend reverting
commit 9f96699c5b62ff1381d8b8838a66329eff2914ce in the ATF repo, which is
the commit
which switched the UART's.

In V2 I've made this configurable :)

regards,

Peter.
