[PATCH 0/3] arm64: Add a build target for Flat Image Tree

From: Simon Glass
Date: Thu Oct 26 2023 - 03:26:42 EST


Flat Image Tree (FIT) is a widely used file format for packaging a
kernel and associated devicetree files. This series adds support for
building a FIT as part of the kernel build. This makes it easy to try
out the kernel - just load the FIT onto your tftp server and it will
run automatically on any supported arm64 board.

The script is written in Python, since it is easy to build a FIT using
the Python libfdt bindings. For now, no attempt is made to compress
files in parallel, so build the 900-odd files takes a while, about
6 seconds with my testing.

The series also includes a few minor clean-up patches.
