[U-Boot] [PATCH v2] x86: Add congatec conga-QA3/E3845-4G (Bay Trail) support
Stefan Roese
sr at denx.de
Wed Mar 16 08:48:21 CET 2016
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

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
