mediatek: add support for Bananapi BPi-R3
The Bananapi BPi-R3 is a development router board built around the MediaTek Filogic 830 (MT7986A) SoC. The board can boot either from microSD, SPI-NAND, SPI-NOR or eMMC. Only either SPI-NAND or SPI-NOR can be used at the same time, also only either microSD or eMMC can be used. The various storage options can be selected using small SMD switches on the board. Specs: * MediaTek MT7986A (Filogic 830) 4x ARM Cortex A53 * 4T4R 2.4G 802.11bgnax (MT7975N) * 4T4R 5G 802.11anac/ax (MT7975P) * 2 GB DDR4 RAM * 8 GB eMMC * 128 MB SPI-NAND flash * 32 MB SPI-NOR flash * on-board MT7531 GbE switch * 2x SFP+ (1 GbE / 2.5 GbE) * 5x GbE network port * miniPCIe slot (only USB 2.0 connected) * uSIM slot (connected to miniPCIe interface) * M.2 KEY-E PCIe interface (PCIe x2) * microSD card interface * 26 PIN GPIO Hardware details: https://wiki.banana-pi.org/Banana_Pi_BPI-R3 Working: * all 4 boot methods incl. installation via U-Boot, sysupgrade, ... * copper LAN and WAN ports * SFP1 (connected to gmac1, eth1 in Linux) * WiFi * LEDs * Buttons * PSTORE/ramoops based dual-boot Not Working (missing driver features): * SFP2 (connected to MT7531 switch) Untested: * M.2/NGFF slot (PCIe x2) * mPCIe slot (USB 2.0 + SIM) Signed-off-by: Daniel Golle <daniel@makrotopia.org>
