+# Portwell PQ7-M107
+
+This page describes how to run coreboot on the [Portwell PQ7-M107].
+
+PQ7-M107 are assembled with different onboard memory modules:
+ Rev 1.0 Onboard Samsung K4B8G1646D-MYKO memory
+ Rev 1.1 and 1.2 Onboard Micron MT41K512M16HA-125A memory
+
+Use 'make menuconfig' to configure `onboard memory manufacture` in Mainboard
+menu.
+
+## Required blobs
+
+This board currently requires:
+fsp blob 3rdparty/fsp/BraswellFspBinPkg/FspBin/BSWFSP.fd
+Microcode Intel Braswell cpuid 1046C4 version 410
+ (Used pre-built binary retrieved from Intel site)
+
+## Flashing coreboot
+
+### Internal programming
+
+The main SPI flash can be accessed using [flashrom].
+
+### External programming
+
+The system has an internal flash chip which is a 8 MiB soldered SOIC-8 chip.
+This chip is located on the top middle side of the board. It's located
+between SoC and Q7 connector. Use clip (or solder wires) to program
+the chip.
+Specifically, it's a Winbond W25Q64FW (1.8V), whose datasheet can be found
+[here][W25Q64FW].
+
+## Known issues
+
+- The PQ7 module contains Q7 connector only. Depending on the carrier
+serial/video/pcie ports might be available.
+
+## Untested
+
+- hardware monitor
+- SDIO
+- Full Embedded Controller support
+
+## Working (using carrier)
+
+- USB
+- Gigabit Ethernet
+- integrated graphics
+- flashrom
+- external graphics
+- PCIe
+- eMMC
+- SATA
+- serial port
+- SMbus
+- HDA (codec on carrier)
+- initialization with FSP MR2
+- SeaBIOS payload (version rel-1.11.0-44-g7961917)
+- Embedded Linux (Ubuntu 4.15+)
