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 (coming from Dario). 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. Move BSH board using the spl loading instead
the romapi

Michael Trimarchi (5):
  nand: raw: mxs_nand: Fix specific hook registration
  mtd: nand: mxs_nand_spl: Fix bad block skipping
  arm: mach-imx: cmd_nandbcb fix bad block handling
  spl: spl_nand: Fix bad block handling in fitImage
  board: bsh: Switch to nand spl load instead of romapi
