14.8.22 VIRAL
This register provides the option to generate viral alert upon the detection of fatal error.
Note: 
• Bit 0 and Bit 2 must be set to b’1 to enable viral.
• Bit 1 must be set to b’1 IF and ONLY IF BIOS also enables IOMCA in Viral mode. If 
IOMCA is disabled, then leave the bit at default of b’0.

iio_viral_state:
Indicates the IIO cluster is in a viral state. When set, all outbound requests 
are master aborted, all inbound requests are master aborted. This includes 
traffic to and from the DMI port, except the Reset_Warn message, which 
will be auto-completed by the DMI port.
If cleared by software by setting a ‘1’, the IIO cluster will exit the viral state. 
This state bit is cleared by warm reset.

iio_viral_status:
Indicates the IIO cluster had gone to viral. This bit has no effect on 
hardware and does not indicate the IIO is currently in the viral state. This 
bit is persistent through warm reset (sticky), even though the viral state is 
not.

iio_signal_global_fatal: 
Enables IIO to signal Global Fatal for an internal fatal error.
When in Viral mode and IOMCA is enabled, this will result in signaling 
CATERR# when IIO detects an internal fatal error. 
Note that CATERR# assertion in this case will be in addition to assertion of 
IIO ERRx# pin.

iio_fatal_viral_alert_enable:
