<content type='text'>
Add support for devices that expose a TPMv2 though MMIO.
Apart from those devices, we can use the driver in our QEMU setups and
test TPM related code which is difficult to achieve using the sandbox
driver (e.g test the EFI TCG2 protocol).

It's worth noting that a previous patch added TPMv2 TIS core functions,
which the current driver is consuming.

H1 is a Google security chip present in recent Chromebooks, Pixel phones
and other devices. Cr50 is the name of the software that runs on H1 in
Chromebooks.

This chip is used to handle TPM-like functionality and also has quite a
few additional features.

Add a driver for this.

<title>tpm: allow TPM v1 and v2 to be compiled at the same time</title>

While there is probably no reason to do so in a real life situation, it
will allow to compile test both stacks with the same sandbox defconfig.

As we cannot define two 'tpm' commands at the same time, the command for
TPM v1 is still called 'tpm' and the one for TPM v2 'tpm2'. While this
is the exact command name that must be written into eg. test files, any
user already using the TPM v2 stack can continue to do so by just writing
'tpm' because as long as TPM v1 support is not compiled, U-Boot prompt
will search for the closest command named after 'tpm'.

The command set can also be changed at runtime (not supported yet, but
ready to be), but as one can compile only either one stack or the other,
there is still one spot in the code where conditionals are used: to
retrieve the v1 or v2 command set.
