libfdt does provide unaligned access helpers (fdt32_ld() etc.), but

usually doesn't need to do further modifications, unlike a
I suspect what Alexey was suggesting though, was merely to make
ms::fdt accessible as a single bytestring property on the machine QOM

So

If you're going for dts like output, I'd suggest going all the way.
That means \" instead of \' and a ';' at the end of the line.

fdt_pack() could change (reduce) the effective size of the dtb blob,
so returning a 'size' value from above rather than the new value of
fdt_totalsize(fdt) doesn't see right.
