Hi,

Sorry, I forgot to report the Reviewed-by of Miquel Raynal.


> Objet: [PATCH V3 2/2] cmd: tpm: add a subcommand device

> The command tpm (and tpm2) search the tpm and use it.
> On sandbox, there are two tpm (tpm 1.x and tpm 2.0).
> So the command tpm and tpm2 are always executed with
> the first tpm (tpm 1.x), and the command tpm2 always
> fails.
>
> This add a subcommand device to command tpm and
> command tpm2. Then the command tpm and tpm2 use
> the device selected with the subcommand device.
>
> To be compatible with previous behaviour, if the
> subcommand device is not used before a tpm (or tpm2)
> command, the device 0 is selected.
