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 --- v2: - Rebased on u-boot-x86/master - Fixed spelling of Bay Trail in commit subject - Removed unreferenced CONFIG_WINBOND from config header - Moved Intel E1000 from config header to defconfig
