libfdt: Add setprop_placeholder & Improve trimprop
Add a wrapper for the previously unsupported fdt_setprop_placeholder().
As fdt_setprop() internally calls fdt_setprop_placeholder()+memcpy(),
the previous implementation of trimprop() was effectively resulting in
fdt_setprop_placeholder(..., len, ...);
memcpy(data, data, len);
for which it needed to use getprop_internal() to play some tricks around
the borrow checker to make that memcpy have no effect. Instead, simply
implement it by calling fdt_setprop_placeholder() directly, making the C
calls more efficient and the Rust code simpler and safer.
Test: m pvmfw
Test: atest liblibfdt.integration_test

Android Virtualization Framework (AVF) provides secure and private execution environments for executing code. AVF is ideal for security-oriented use cases that require stronger isolation assurances over those offered by Android’s app sandbox.
Visit our public doc site to learn more about what AVF is, what it is for, and how it is structured. This repository contains source code for userspace components of AVF.
If you want a quick start, see the getting started guideline and follow the steps there.
