It depends on what you want from qemu.

For example, I use qemu to check that the firmware image is bootable and works
fine:
```
qemu-system-arm -M ast2500-evb -m size=512M \
    -nographic -nodefaults -serial mon:stdio \
    -net nic,model=ftgmac100 \
    -drive file=<path-to-image-mtd>,format=raw,if=mtd
```

This way has some failures:
 - There is emulated MTD falsh drive only 32M size. As a result fit-image-b and
   u-boot-env partitions are unreadable.
 - There is no managed host. So there are not work the host power state
   management, KVM, Virtual Media and so on. 

Probably there are more failures, which I have not noticed.

While writing these lines I remembered that I use qemu-system-arm, built from
source on https://github.com/openbmc/qemu.
It's important, because the qemu-system-arm from my distro is too old and this
image is not working with it.

I was looking for something like a -M wolfpass-bmc command line option like Romulus has -M romulus-bmc
(see here: https://github.com/openbmc/docs/blob/master/development/dev-environment.md )

Yet I find no wolfpass, S2600WF, nor Intel in the -machine help list. (see below)

Yes, there is no full implemented platform.

As I know, the wolfpass bmc based on aspeed ast2500 SoC. 
I can't remember why I choose exactly ast2500-evb for the tests of wolfpass.
Probably it was reported somewhere in the internal documents.

If someone has other experience or more knowledge please share it.

Alexander.

Hello,

You can use the ast2500-evb as a base to add a model that matches the WolfPass configuration as closely as possible.

Usually, it works quite well to model that part of the BMC that you are developing software for. Full implementation is possible of course but most likely a lot of work.

We would need a machine definition such as the ones in hw/arm/aspeed.c.

See :

https://git.qemu.org/?p=qemu.git;a=blob;f=hw/arm/aspeed.c;h=a6a2102a93cbe2199c28e58deee480518076476e;hb=HEAD#l472

in the limited scope of what QEMU supports. I2C models are not too
complex to write if someone is interested.

Regards,

C.
