+Subject: [PATCH 1/1] x86: serial: ns16550: Allow the UART to be silently
+ disabled
+
+U-Boot normally requires a UART. When booting from coreboot it is
+sometimes just not available, e.g. when no sysinfo or DBG2 information
+is provided.
+
+In this case we need to continue running, since the display can be used.
+Add a flag to disable serial for this case.
+
+This allows U-Boot to start up and operation from the display, instead
+of hanging on start-up.
+
+This could perhaps be hidden behind a Kconfig option to reduce code
+size.
