[PATCH] doc: qemu: switch swtpm instruction to 'tpm autostart'
We don't have a documentation page for our TPM subsystem. I plan on sending one in the future, but in the meantime document the new 'tpm autostart' command in the QEMU instructions while using a SWTPM

Do you really intend switch from TPM v2 to the deprecated TPM v1?
I assume you mean "tpm2 autostart".

Both tpm v1/v2 commands will call do_tpm(). That function will properly call a v1 or v2 API depending on the device it discovered. So the autostart function will work for both variants correctly.
P.S: Looking at commit e663b2ff4ba2("tpm: Add 'tpm autostart' shell command"), I apparently messed up a c/p and autostart is missing from the v1 version of the command. I'll send a patch to fix that
Thanks /Ilias
