- List-id: Xen developer discussion <xen-devel.lists.xenproject.org>
early_uart_init macro is only used if CONFIG_EARLY_UART_INIT is set.
This config option depends on EARLY_UART_PL011, so there is no point
in defining it for MESON, especially if it is empty. Remove it and adapt
the existing comment.
