[Qemu-devel] [PATCH v2 00/20] hw/i386/pc: Do not restrict the fw_cfg functions to the PC machine

[Philippe Mathieu-Daudé]

Hi,

This is my take at salvaging some NEMU good work.
Samuel worked in adding the fw_cfg device to the x86-virt NEMU machine.
This series is inspired by NEMU's commit 3cb92d080835 [*] and adapted
to upstream style. The result makes the upstream codebase more
modularizable.
There are very little logical changes, this is mostly a cleanup
refactor.

Since v1:
- Addressed Li and MST comments

$ git backport-diff -u v1
Key:
[----] : patches are identical
[####] : number of functional differences between upstream/downstream patch
[down] : patch is downstream-only
The flags [FC] indicate (F)unctional and (C)ontextual differences, respectively
