Please use stdout-path instead (you can use /aliases to make it
simpler). It'll save a redundant description of the UART and will remove
the dependency on Linux-specific naming of the UART.

Shouldn't the other CPUs be described?
Using spin-table for SMP is somewhat unfortunate, as it comes with a
number of problems (e.g. unwoken secondaries spinning in the kernel). I
would strongly advise using PSCI instead.

Please fix your firmware to configure CNTFRQ_EL0, it is simply a bug not
to, and using clock-frequency does not fix all the problems that not
configuring it causes.
Thanks,
Mark.
