[Minios-devel] [UNIKRAFT PATCH 0/8] Add frequently usd APIs to fdt library (series#2)

[Wei Chen <wei.chen@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 serveral APIs in lib/fdt to reduce the
redundant calls of fdt functions.
