+Subject: [PATCH] mtd: parsers: trx: allow to use on MediaTek MIPS SoCs
+
+Buffalo sells some router devices which have trx-formatted firmware,
+based on MediaTek MIPS SoCs. To use parser_trx on those devices, add
+"RALINK" to dependency and allow to compile for MediaTek MIPS SoCs.
+
+examples:
+
+- WCR-1166DS  (MT7628)
+- WSR-1166DHP (MT7621)
+- WSR-2533DHP (MT7621)
