Just keep an eye on the addresses, so that the starting address of an
"item" doesn't step over the previous "item" payload. I'm usually too
lazy to calculate the differences all the time, and just use a 32 MiB
address step, like this:
0x12000000 - kernel
0x13000000 - device tree (or optional initrd)
0x14000000 - (optional device tree if initrd was loaded at 0x13000000)
Thus if all of your items are <= 32 MiB, these addresses will work all
the time.
Regards,
Nikolay
