It is showing errors for serial_hds() and MachineState so what specific  .h files I should add?

I have built custom hardware which is based on arm-m3 in qemu-2.10. It works fine for Hello_world.c a basic program emulation. 

Now I have migrated to qemu-4.2.0. I want to run the same Hello_world.c which is not emulating. 

I have changed the .objs accordingly. What would you suggest?

For the minor machines (that is: not the ones which have version number
suffixes like pc or virt) we do not make a record of changes. Generally
any changes will be either bug fixes to the model, or occasionally
implementation of new features. Akita in particular is not really
very actively maintained, so I don't think it's had any significant

If you have a guest that used to boot and no longer does:
(1) First check whether your guest boots on a modern QEMU (ie the
most recent release, which is 6.0)
(2) If it doesn't boot on 6.0, do a git bisect to try to find
the commit where your guest stopped working. That should help
in identifying what the problem is.
