Merge tag 'fwu-next-26032026' of https://source.denx.de/u-boot/custodians/u-boot-tpm into next
CI: https://source.denx.de/u-boot/custodians/u-boot-tpm/-/pipelines/29677
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.
