5Description:
6		The file exposes "Extended Test Mode Register 3" global
7		reset bits. The bits are used during an Intel platform
8		manufacturing process to indicate that consequent reset
9		of the platform is a "global reset". This type of reset
10		is required in order for manufacturing configurations
11		to take effect.
12
13		Display global reset setting bits for PMC.
14
15			* bit 31 - global reset is locked
16			* bit 20 - global reset is set
17
18		Writing bit 20 value to the etr3 will induce
19		a platform "global reset" upon consequent platform reset,
20		in case the register is not locked.
21		The "global reset bit" should be locked on a production
22		system and the file is in read-only mode.
