Hi, I'm in the process of fixing up imx-kobs to support - boot configuration dumps - boot stream extracts/updates on iMX6QDL using the GPMI-NAND interface, as provided by some more "recent" kernels. I updated barebox on the NAND flash storage using another instance of barebox. Now it turns out that the dbbt version used (i.e. written) by barebox and supported by imx-kobs (as it was) is not documented in the i.MX6 QDL reference manual. Barebox uses[0] DBBT version 0x1000000, while the reference manual describes (i.MX6DQRM Rev 3., section 8.5.2.4) layout version 0x1. Besides that, the reference manual apparently does not describe the field `BBMarkerPhysicalOffsetInSpareData` at the end of the FCB structure. Yet again, imx-kobs and barebox are reading/writing it. So I'm wondering which behavior is correct?
