They should expose suitable properties for the user to set. For onboard devices, board code sets them. Device ssi-sd picks up its block backend in its init() method with drive_get_next() instead. This mistake is already marked FIXME since commit af9e40a. Unset user_creatable to remove the mistake from our external interface. Since the SSI bus doesn't support hotplug, only -device can be affected. Only certain ARM machines have ssi-sd and provide an SSI bus for it; this patch breaks -device ssi-sd for these machines. No actual use of -device ssi-sd is known.

And also it can support the exception state migration. The SError exception states include SError pending state and ESR value, the kvm_put/get_vcpu_events() will be called when set or get system registers. When do migration, if source machine has SError pending, QEMU will do this migration regardless whether the target machine supports to specify guest ESR value, because if target machine does not support that, it can also inject the SError with zero ESR value.

Only master-mode functionality is implemented. The SPL boot for Cubieboard expects AXP209 PMIC on TWI0/I2C0 bus, so this is first part enabling the TWI/I2C bus operation. Since both Allwinner A10 and H3 use the same module, it is added for both boards. Docs are also updated for Cubieboard and Orangepi-PC board to indicate I2C availability.
