The gdsys ControlCenter Digital board is based on a Marvell Armada 38x SOC. It boots from SPI-Flash but can be configured to boot from SD-card for factory programming and testing. On board peripherals include: - 2 x GbE - Xilinx Kintex-7 FPGA connected via PCIe - mSATA - USB3 host - Atmel TPM Signed-off-by: Dirk Eibach <dirk.eibach@gdsys.cc> Signed-off-by: Mario Six <mario.six@gdsys.cc> Signed-off-by: Stefan Roese <sr@denx.de>
