This doesn't fit my Sockit configuration for example. So I would always have to patch the devicetree.I'm not 100% sure on this. Graham, do you have any insight?quoted
Well, strictly speaking, these partitions are only for the socdk, the Altera dev kit. Our sample designs and file systems expect this layout.
The thing is, that I don't think these partitions belong in a mainline dts at all. But I'm not sure what the current policy is.
Therefore, these partitions are not required for any other dev kits, and can probably be left out. Or, Steffen, if you have a standard layout you'd like to see, then put that in there.
Well in my case, it actually doesn't really matter. All the boards I use do not have u-boot as bootloader but barebox. And barebox uses devicetree fixups for adding the partition layout that fits the particular use case. All other partitions are thrown out. I don't know if u-boot does something like this.
