Question. Is there a reason to not being doing the MTDIDS / MTDPARTS and adding CONFIG_CMD_MTDPARTS ?
Yes, MTDIDS/MTDPARTS is missing, however, we can set mtdids and mtdpart environment to use mtdparts command. (Maybe this is not a good idea, will consider to add MTDIDS / MTDPARTS later, not in this patch series.)
Right. But without CONFIG_CMD_MTDPARTS you don't have the mtdparts commands / infrastructure in U-Boot :)
Doing that should also "just" enable the nand info to be passed in the device tree.
I am not fully understand this. You means add MTDIDS / MTDPARTS, it can automatically pass the nand info to device tree, not through the command line, am I right?
I was mis-remembering the code. If you have CONFIG_FDT_FIXUP_PARTITIONS set and the board support code calls fdt_fixup_mtdparts then yes, the mtdparts info will be put into the device tree and then CONFIG_MTD_OF_PARTS in the kernel should take that and run with it. At least I think that's all there is to it, I've meant to, but not had a chance, to try that all out again. Perhaps soon tho.
