-Subject: [PATCH] mtd: bcm47xxpart: move TRX parsing code to separated function
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-This change simplifies main parsing loop logic a bit. In future it may
-be useful for moving TRX support to separated module / parser (if we
-implement support for them at some point).
-Finally parsing TRX at the end puts us in a better position as we have
-better flash layout knowledge. It may be useful e.g. if it appears there
-is more than 1 TRX partition.
