I'm running a custom kernel on a custom board based on mx25.
It has a 2GB micron nand flash.(2k+64B spare)
Kernel is based freescale L2.6.28 release.
I became aware of the SwapBBI issue/feature with the NFC(attached document), when investigating nand corruption issues.
The newer releases have a swap BBI feature in the mxc nand driver.
My query is: Is this applicable to MX25 so that I can back port the driver?
Obviously I would need to propagate the changes to boot loader and factory flash programmer.
In some forums, I read that it would be applicable to only imx31 and imx27 and hence the confusion.
Yes, you can back port the swap bbi driver from newer bsp to older bsp, include kernel, uboot and factory flash programmer.
