+Subject: [PATCH] ARM: BCM5301X: Enable UART0 on tested devices
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+There are two possible UARTs so we have (both of) them disabled by
+default. Override uart0 status on devices that were verified to use it.
+In case of Netgear R6250 also drop an old (and invalid) overwrite. It
+doesn't have uart1 connected.
