Be very careful when you change ECC layouts. This can break production systems. For example if people are running something earlier and then want to deliver a new kernel with 2.6.37 then their existing NAND file systems will no longer be readable. Changes to ECC should only be done for very good reasons and should be controlled with a Kconfig with the default being the existing ECC layout. [Ghorai] we are just adding few ecc-layout(s) and based on the request from different customer. The default ecc-layout is the old one for backward compatibility and selection of ecc-layput is exposed form board file. -- To unsubscribe from this list: send the line unsubscribe linux-omap in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
