   4 Subject: [PATCH 1/6] ARM: BCM5301X: Enable UART by default for BCM4708(1),
   5  BCM4709(4) & BCM53012
   6 MIME-Version: 1.0
   7 Content-Type: text/plain; charset=UTF-8
   8 Content-Transfer-Encoding: 8bit
   9
  10 Every device tested so far got UART0 (at 0x18000300) working as serial
  11 console. It's most likely part of reference design and all vendors use
  12 it that way.
  13
  14 It seems to be easier to enable it by default and just disable it if we
  15 ever see a device with different hardware design.
