Just adding few more info from what I see.\nOPAL was stuck at cec-power-down, since it expects an ipmi-bt device for\nshutdown to work in QEMU.\n\nSo, the issue was not directly due to missing BMC device, rather due to\nmissing 'isa-ipmi-bt' device, which the patch does fix, and hence the\nissue is fixed.\n\nBut still the dts we have is different from what we should have at\npnv_reset. Adding a pnv_dt_create at the end of pnv_reset, as it used to\nbe before, gives me a 'bmc' node also in device tree.\n\n\t$ diff /tmp/dts.machinedone /tmp/dts.pnvreset \n\t16a17,33\n\t> bmc {\n\t> \n\t> sensors {\n\t> #size-cells = <0x00>;\n\t> #address-cells = <0x01>;\n\t> \n\t> sensor@0 {\n\t> ipmi-sensor-type = <0x23>;\n\t> ipmi-entity-instance = <0x01>;\n\t> ipmi-entity-id = <0x23>;\n\t> ipmi-sensor-reading-type = <0x6f>;\n\t> compatible = \"ibm,ipmi-sensor\";\n\t> reg = <0x00>;\n\t> };\n\t> };\n\t> };\n\t> \n\nThis isn't handled at machine_init_done as 'pnv->bmc' is not set at this\ntime\n\nTwo ways to fix it:\n1.
