From 5c9b26378e5b80cc876ec2515047d8b2759ff47c Mon Sep 17 00:00:00 2001 From: Sascha Hauer Date: Fri, 11 Mar 2016 11:08:09 +0100 Subject: imx-bbu-nand-fcb: When writing firmware return new bad blocks Positive return values of imx_bbu_write_firmware() so far indicate the last block that has been written to. This value is unused, so return values > 0 to indicate if there are new bad blocks. This information can be used in the next step to know if the DBBT has to be rewritten.
