[Minios-devel] [UNIKRAFT PATCHv10 0/7] Add frequently usd APIs to fdt(series#2)

[Jia He <justin.he@xxxxxxx>]

Arm64 devices libraries will access device tree to get lots of
properties. We will get device addresses, interrupts in each device
library. In this case, we will find device node by offset, get address
cells, size cells and interrupt cells everywhere.

This patch series introduces several APIs in lib/fdt to reduce the
redundant calls of fdt functions.

v5->v6:
  fix one small compilation warning in patch 07
