[Qemu-devel] [PATCH qemu v2] aspeed: Add support for the swift-bmc board
Posted by Adriana Kobylak 4 years, 10 months ago 
From: Adriana Kobylak <anoo@us.ibm.com>

The Swift board is an OpenPOWER system hosting POWER processors.
Add support for their BMC including the I2C devices as found on HW.

I pushed this patch in my tree for the moment as the patchset :

  "aspeed: machine extensions and fixes" patchwork.ozlabs.org/cover/1105343/

still needs some more reviews.

Thanks,
