+Description:	Remote processor name
57
+
58
+		Reports the name of the remote processor. This can be used by
59
+		userspace in exactly identifying a remote processor and ease
60
+		up the usage in modifying the 'firmware' or 'state' files.

+Description:	Remote processor coredump configuration
66
+
67
+		Reports the coredump configuration of the remote processor,
68
+		which will be one of:
69
+
70
+		"disabled"
71
+		"enabled"
72
+		"inline"
73
+
74
+		"disabled" means no dump will be collected.
75
+
76
+		"enabled" means when the remote processor's coredump is
77
+		collected it will be copied to a separate buffer and that
78
+		buffer is exposed to userspace.
79
+
80
+		"inline" means when the remote processor's coredump is
81
+		collected userspace will directly read from the remote
82
+		processor's device memory. Extra buffer will not be used to
83
+		copy the dump. Also recovery process will not proceed until
84
+		all data is read by usersapce.

+Description:	Remote processor recovery mechanism
90
+
91
+		Reports the recovery mechanism of the remote processor,
92
+		which will be one of:
93
+
94
+		"enabled"
95
+		"disabled"
96
+
97
+		"enabled" means, the remote processor will be automatically
98
+		recovered whenever it crashes. Moreover, if the remote
99
+		processor crashes while recovery is disabled, it will
100
+		be automatically recovered too as soon as recovery is enabled.
101
+
102
+		"disabled" means, a remote processor will remain in a crashed
103
+		state if it crashes. This is useful for debugging purposes;
104
+		without it, debugging a crash is substantially harder.
