+The Freescale downstream vendor kernel has a patch that exports the bch
+flash geometry via a debugfs file. This is not available in mainline linux
+kernels so the fallback method calculates the geometry based on known info
+from the mtd partition. A bug exists in this funcion where it fails to
+assume that block0 ECC is the same as the other blocks by default.
