There is nothing in this commit except for the changes made by nix-shell -p nixfmt-rfc-style --run "nixfmt ." If this has mucked up your open branches then sorry about that. You can probably nixfmt them to match before merging

QEMU ARM v7
|
|
***********
|
|
|
|
This target produces an image for
|
|
the `QEMU "virt" platform <https://www.qemu.org/docs/master/system/arm/virt.html>`_ using a 32 bit CPU type.
|
|
|
|
ARM targets differ from MIPS in that the kernel format expected
|
|
by QEMU is an "Image" (raw binary file) rather than an ELF
|
|
file, but this is taken care of by :command:`run.sh`. Check the
|
|
documentation for the :ref:`QEMU` (MIPS) target for more information.
