   4 Subject: arm: mvebu: add uartX labels for Armada SoC serial nodes
   5
   6 This patch adds uartX labels for Armada SoC serial nodes. This is
   7 a preliminary work to be able to easily reference the serial lines
   8 in Device Tree files. One expected use is when providing stdout-path
   9 property for barebox.
