They appear to require some special configuration as well; presumably the firmware performs this configuration and enables a compatibility mode for CSM booting. Just adding the PCI device IDs is not sufficient. none7@pci0:0:30:3: class=0x078000 card=0x72708086 chip=0x0f0a8086 rev=0x0c hdr=0x00 vendor = 'Intel Corporation' device = 'ValleyView LPIO1 HSUART Controller' class = simple comms cap 01[80] = powerspec 3 supports D0 D3 current D0 none8@pci0:0:30:4: class=0x078000 card=0x72708086 chip=0x0f0c8086 rev=0x0c hdr=0x00 vendor = 'Intel Corporation' device = 'ValleyView LPIO1 HSUART Controller' class = simple comms cap 01[80] = powerspec 3 supports D0 D3 current D0 Related Linux commits are b15e5691 and 29897087 -- You are receiving this mail because: You are the assignee for the bug.
