v2025.08.0

[Sascha Hauer]

Hi All,

barebox-2025.08.0 is out now.

This release brings us readonly data segments on ARM. With this data
readonly data cannot be modified and only the code segments can be
executed. Violation gives us aborts which is good for improving security
and will help debugging.

Also we now have a createnv command. This command creates a barebox
environment partition on disk devices (eMMC/SD). barebox recognizes
environment partitions on GPT formatted disks for longer. While these
can be easily generated with YOCTO/ptxdist/buildroot, it was not so easy
when barebox is used without a build system on a unpartitioned device.
Now with createnv this is also easily possible, so adding the
environment partiton to the device tree becomes more and more
unnecessary.

Another nice this is that on ARM we now have exception handling support.
This was originally done to detect if we can access the TZASC on i.MX6
in order to configure it, but in the end this can become really useful
to debug PBL code.

Other than that many patches all over the place went into this release,
see below.

Have Fun!
 Sascha
