From 02673659e81391729792ebc1b816d974de3c9abf Mon Sep 17 00:00:00 2001 From: Kory Maincent Date: Mon, 23 Feb 2026 14:18:39 +0100 Subject: tools: Add support for fwumdata tool Add a new fwumdata tool to allows users to read, display, and modify FWU (Firmware Update) metadata from Linux userspace. It provides functionality similar to fw_printenv/fw_setenv but for FWU metadata. Users can view metadata, change active/previous bank indices, modify bank states, and set image acceptance flags. Configuration is done via fwumdata.config file.
