This patch adds support for the congatec conga-QA3/E3845-4G eMMC8 SoM, installed on the congatec Qseven 2.0 evaluation carrier board (conga-QEVAL). Its port is very similar to the MinnowboardMAX port and also uses the Intel FSP as described in doc/README.x86. Currently supported are the following interfaces / devices: - UART (via Winbond legacy SuperIO chip on carrier board) - Ethernet (PCIe Intel I210 / E1000) - SPI including SPI NOR as boot-device - USB 2.0 - SATA via U-Boot SCSI IF - eMMC - Video (HDMI output @ 800x600) - PCIe Not supported yet is: - I2C - USB 3.0 Signed-off-by: Stefan Roese <sr@denx.de> Cc: Simon Glass <sjg@chromium.org> Cc: Bin Meng <bmeng.cn@gmail.com> Reviewed-by: Bin Meng <bmeng.cn@gmail.com>
