This is a small libpdbg application that reads LPC FW space on a Power9/Power10 using scoms. It can run on the BMC or the host.
It is implemented as a Rust application calling in to the C libpdbg API.

The project includes copies of libfdt and libpdbg built for ARMv7 hard float, and PowerPC 64bit little endian.
