   4 Subject: [PATCH] ARM: mvebu: add Linksys WRT1900AC (Mamba) support
   5
   6 The Linksys WRT1900AC (Mamba) is a router that has
   7
   8 - 2 mini-PCIe slots with Marvell 88W8864 radios
   9 - 1 USB 3.0 port
  10 - 1 USB 2.0/eSATAp port
  11 - 2 Ethernet interfaces connected to a 88E6172 switch (1x WAN + 4x LAN)
  12 - 128MB NAND flash
  13 - 256MB RAM
  14
  15 gregory.clement@free-electrons.com: - add ARM to the title
  16         - fix the reference to CONFIG_DEBUG_MVEBU_UART0_ALTERNATE
  17         - fix the unbalanced comment for the syscfg partition
