ramips: add support for VoCore2
This patch adds support for the VoCore VoCore2 and its complementary "ultimate" dock. Specifications: - SoC: MediaTek MT7628AN (580MHz, ramips) - RAM: 128MB DDR2 166MHz - Storage: 16MB NOR SPI flash onboard + microSD slot on dock - Wireless: Built into MT7628AN (mt76) with 1T1R firmware on VoCore2 boards with onboard 1x chip antenna - Ethernet: 1x100M (port0) on dock, 1x100M (port2) on PCB header - Dock hardware: - USB 2.0 socket - MicroSD socket - 100Mbps Ethernet x1 - 3.5mm headphone jack (TRRS) connected to Everest Semi ES8388 I2S DAC/ADC (support WIP) - Micro USB for power and console (UART2) Initial installation: - VoCore2 comes preinstalled with a fork of OpenWrt CC and AP on SSID "VoCore2" - Connect to VoCore2 by Ethernet or Wi-Fi - `ssh root@192.168.1.1` (password is "vocore") - scp/wget/etc. LEDE sysupgrade.bin to VoCore2 - `sysupgrade -n <your image>.bin` (don't keep old config, as the original firmware uses Ralink SDK Wi-Fi drivers and not mt76+mac80211) - after sysupgrade completes, Wi-Fi will be disabled by default so use Ethernet or the micro USB console to configure Wi-Fi again Signed-off-by: Andrew Yong <me@ndoo.sg>v19.07.3_mercusys_ac12_duma
