ifdtool: Add locking/unlocking and dumping of access permissions
ifdtool will now dump access permissions of system comonents to certain IFD sections: Found Master Section FLMSTR1: 0xffff0000 (Host CPU/BIOS) Platform Data Region Write Access: enabled GbE Region Write Access: enabled Intel ME Region Write Access: enabled Host CPU/BIOS Region Write Access: enabled Flash Descriptor Write Access: enabled Platform Data Region Read Access: enabled GbE Region Read Access: enabled Intel ME Region Read Access: enabled Host CPU/BIOS Region Read Access: enabled Flash Descriptor Read Access: enabled Requester ID: 0x0000 FLMSTR2: 0x0c0d0000 (Intel ME) Platform Data Region Write Access: disabled GbE Region Write Access: enabled Intel ME Region Write Access: enabled Host CPU/BIOS Region Write Access: disabled Flash Descriptor Write Access: disabled Platform Data Region Read Access: disabled GbE Region Read Access: enabled Intel ME Region Read Access: enabled Host CPU/BIOS Region Read Access: disabled Flash Descriptor Read Access: enabled Requester ID: 0x0000 FLMSTR3: 0x08080118 (GbE) Platform Data Region Write Access: disabled GbE Region Write Access: enabled Intel ME Region Write Access: disabled Host CPU/BIOS Region Write Access: disabled Flash Descriptor Write Access: disabled Platform Data Region Read Access: disabled GbE Region Read Access: enabled Intel ME Region Read Access: disabled Host CPU/BIOS Region Read Access: disabled Flash Descriptor Read Access: disabled Requester ID: 0x0118 Also, ifdtool -u /path/to/image will unlock the host's access to the firmware descriptor and ME region. ifdtool -l /path/to/image will lock down the host's access to the firmware descriptor and ME region.
