Hey Simon
Thanks for the clarification
Just out of curiosity, how can the padding help modify the FDT in u-boot ?
If you insert a new node/property, or change a property for a longer value, the FDT blob will get longer. So, you need some extra space for modification. Otherwise, the U-Boot image will be overritten in case of CONFIG_OF_EMBED.
But, as Simon said, U-Boot never modifies a FDT that is used to configure U-Boot itself.
Just in case, let me add a little more explanation: What is confusing is, U-Boot can modify a FDT that is passed to the kernel. U-Boot can have two different instances of FDTs: one for configuring U-Boot and the other for configuring Linux. We are talking about the former in this thread.
