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