3This page describes how to run coreboot on the [Portwell PQ7-M107].
4
5PQ7-M107 are assembled with different onboard memory modules:
6	Rev 1.0	Onboard Samsung K4B8G1646D-MYKO memory
7	Rev 1.1 and 1.2 Onboard Micron MT41K512M16HA-125A memory
8	Rev 1.3	Onboard Kingston B5116ECMDXGGB memory

13## Required blobs
14
15This board currently requires:
16fsp blob	3rdparty/fsp/BraswellFspBinPkg/FspBin/BSWFSP.fd
17Microcode	3rdparty/intel-microcode/intel-ucode/06-4c-04

19## Flashing coreboot
20
21### Internal programming
22
23The main SPI flash can be accessed using [flashrom].
24
25### External programming
26
27The system has an internal flash chip which is a 8 MiB soldered SOIC-8 chip.
28This chip is located on the top middle side of the board. It's located
29between SoC and Q7 connector. Use clip (or solder wires) to program
30the chip.
31Specifically, it's a Winbond W25Q64FW (1.8V), whose datasheet can be found
32[here][W25Q64FW].
