 		Reports the name of the remote processor. This can be used by
 		userspace in exactly identifying a remote processor and ease
 		up the usage in modifying the 'firmware' or 'state' files.

+Description:	Remote processor coredump configuration
+
+		Reports the coredump configuration of the remote processor,
+		which will be one of:
+
+		"default"
+		"inline"
+		"disabled"
+
+		"default" means when the remote processor's coredump is
+		collected it will be copied to a separate buffer and that
+		buffer is exposed to userspace.
+
+		"inline" means when the remote processor's coredump is
+		collected userspace will directly read from the remote
+		processor's device memory. Extra buffer will not be used to
+		copy the dump. Also recovery process will not proceed until
+		all data is read by usersapce.
+
+		"disabled" means no dump will be collected.
+
+		Writing this file controls the coredump configuration of the
+		remote processor. The following configurations can be written:
+
+		"default"
+		"inline"
+		"disable"
+
+		Writing "default" will change the coredump configuration to
+		default option.
+
+		Writing "inline" will change the coredump configuration to
+		inline.
+
+		Writing "disable" will disable the coredump collection for
+		that remoteproc.
