[PATCH] aspeed: Add support for the sonorapass-bmc board |
Date: |
Fri, 1 May 2020 06:37:04 -0500 |
Sonora Pass is a 2 socket x86 motherboard designed by Facebook
and supported by OpenBMC. Strapping configuration was obtained
from hardware and i2c configuration is based on dts found at:
https://github.com/facebook/openbmc-linux/blob/1633c87b8ba7c162095787c988979b748ba65dc8/arch/arm/boot/dts/aspeed-bmc-facebook-sonorapass.dts
Booted a test image of http://github.com/facebook/openbmc to login
prompt.
