This two-part patch for supermin implements device trees (for ARM).
The first patch introduces a more rational way to handle command line
arguments in 'supermin-helper'. See the commit message for details.
The old style is still supported for compatibility.
The second patch adds an extra supermin-helper --dtb parameter
specifying a wildcard. A device tree file which matches the selected
kernel and this wildcard is linked to (or copied if --copy-kernel).
The intended use is from libguestfs (on ARM) which can now do:
supermin-helper -f ext2 --dtb 'vexpress-*a9.dtb' [etc]
which will create a 'dtb' file alongside kernel, initrd, etc in the
appliance directory. Qemu is invoked using:
qemu-system-arm -kernel kernel -dtb dtb [...]
(or the equivalent via libvirt).
Rich.
