Nit: please remove the spacing around the '<' and '>' here. If nothing
else, it's inconsistent with the rest of this file.

Likewise.

Please use a label for the serial node, have an alias, and describe the
pre-configured rate per the stdout-path binding, e.g.
aliases {
serial0 = &uart0;
};
chosen {
stdout-path = "serial0:19200n8";
};
...
soc@abcd0000 {
...
uart0: serial@100 {
...
};
};
Note that using stdout-path is preferable to current-speed or other
UART-specific bindings.
Thanks,
Mark.
