This patchset adds support for the Libretech cottonwood board family. The 2 boards are based on the same PCB, with an RPi B form factor. The "Alta" board uses an a311d while the "Solitude" variant uses an s905d3. This patchset depends on the usb support for the gl3510 [1] and [6] Without it, there will be dt check warnings and usb may not come up properly. Early u-boot support may be found here [2]. It will be submitted after DT is accepted in Linux. As usual with Amlogic, u-boot must be packaged with closed source binaries ([3] for the a311d, [4] for the s905d3) Prebuilt bootloaders are available from libretech [5]. The devices are shipped with libretech's u-boot pre-flashed in SPI NOR. If necessary, the boot source may be changed to MMC using the onboard switch. Happy hacking ...
