Pull request for fwu-next-26032026

[Ilias Apalodimas]

Hi Tom

Kory added a userspace tool to modify the fwu metadata from linux userspace.
Although this was originally designed to work with UEFI, there are uses cases
where people use it, but boot without EFI.

The following changes since commit 8813d74163e4d84dbd4fb30d9639f01c0acb6d39:

  Merge patch series "test/py: gpio: cleanups and improvement" (2026-03-25 14:38:28 -0600)

----------------------------------------------------------------
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.
