From: Peter Delevoryas <p...@fb.com> This adds a new machine type "fuji-bmc" based on the following device tree:
https://github.com/torvalds/linux/blob/40cb6373b46/arch/arm/boot/dts/aspeed-bmc-facebook-fuji.dts Most of the i2c devices are not there, they're added here: https://github.com/facebook/openbmc/blob/fb2ed12002fb/meta-facebook/meta-fuji/recipes-utils/openbmc-utils/files/setup_i2c.sh I tested this by building a Fuji image from Facebook's OpenBMC repo, booting, and ssh'ing from host-to-guest.
