The tacoma-bmc machine was a board including an AST2600 SoC based BMC

machine which is part of a real product offering.

I have been using tacoma-bmc to test tcg,tpm-tis-i2c functionality
on arm. rainier-bmc doesn't support that, and other IBM BMCs which
do support it (bonnell, everest, system1) are not supported in qemu.
Do you have a suggested alternative ?
Could you use the ast2600-evb machine instead ? as done in
machine_aspeed.py, see routine test_arm_ast2600_evb_buildroot_tpm.
Unfortunately, that does not work for me because that requires instantiating
the tpm chip from the CLI by writing into the new_device sysfs attribute,
and I can not do that in my test environment.
We can't add a "tpm-tis-i2c" device to the tacoma-bmc machine init
routine because a TPM backend is required.
Not sure I understand; tacoma-bmc instantiates the TPM chip through its
devicetree file which is what I was looking for.
I solved the problem by adding support for IBM Bonnell (which instantiates
the TPM chip through its devicetree file, similar to tacoma-bmc) to my local
copy of qemu. It isn't perfect since I don't know the correct HW pin strapping
and reused the strapping from Rainier, but it works for me.
Thanks,
