ramips: Add support for the GnuBee Personal Cloud Two The GnuBee Personal Cloud Two crowdfunded on https://www.crowdsupply.com It is a low-cost, low-power, network-attached storage device. Specifications: - SoC: MediaTek MT7621AT - RAM: DDR3 512 MB - Flash: 32 MB - Six SATA ports for 3.5" Drives - One SDcard - One USB 3.0 - Two USB 2.0 - Gigabit Ethernet: Three Ports - UART 3.5mm Audio Jack or 3 pin header - 57600 8N1 - Three GPIOs available on a pin header Flash instructions: The GnuBee Personal Cloud Two ships with libreCMC installed. libreCMC is a Free Software Foundation approved fork of LEDE/OpenWrt. As such one can upgrade using the webinterface or sysupgrade. Das U-Boot has multiple options for recovery or updates including : - USB - http - tftp Errata: - While there are three ethernet ports, the third requires support for the second GMAC. This will come in kernel 4.14. - The first hard drive slot has a clearance issue with the two fan headers. Workaround is to pull the headers out and connect the pins to jumper wires. - Using this device as a NAS is problematic with the 4.9 kernel as many /dev/sdX reads throw silent errors. The current theory behind this is some kind of unhandled DMA mapping error in the kernel. This is not an issue with kernel 4.4. Signed-off-by: L. D. Pinney Signed-off-by: Rosen Penev
