From: Dirk Eibach dirk.eibach@gdsys.cc
The gdsys hrcon board is based on a Freescale MPC8308 SOC. It boots from NOR-Flash, kernel and rootfs are stored on SD-Card.
On board peripherals include: - 1x GbE (optional) - Lattice ECP3 FPGA connected via eLBC and PCIe
Signed-off-by: Dirk Eibach dirk.eibach@gdsys.cc ---
Changes in v2: - move cmd_ioloop from common to board/gdsys/common - remove debug code from hrcon.c
