-Subject: [PATCH] mtd: bcm47xxpart: support layouts with multiple TRX
- partitions
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-Some devices may have an extra TRX partition used as failsafe one. If
-we detect such partition we should set a proper name for it and don't
-parse it.
