-Subject: mtd: parsers: trx: Allow to specify trx-magic in DT
-
-Buffalo uses a different TRX magic for every device, to be able to use
-this trx parser, make it possible to specify the TRX magic in device
-tree. If no TRX magic is specified in device tree, the standard value
-will be used. This value should only be specified if a vendor chooses to
-use a non standard TRX magic.
