Those patches come after some testing of failing in factory on some unit. We found out that the bootrom imx loader was not able to handling badblock. This can be a limit of the implementation right now in imx8mn. Anyway not all the imx platform has the support of this loader. I found some problems on the implementation so I have fixed it up according the experience of Sitara. I tested only using a Fit Image as a flash container. This version add in the series the fix of cmd_nandbcb and the fix of spl_nand load. I can imagine that a lot of boards and users are affected. I have started to backport this changes in some older uboot and adapt it
