[SeaBIOS] [PATCH 00/10] Some TPM simplifications

[Kevin O'Connor]

The following series involves some code reorganization in the TPM code
that I found useful in understanding the code.

Patches 3-5 simplify the hardware interface by only exporting three
commands to the underlying TIS hardware (tpmhw_probe, tpmhw_transmit,
tpmhw_set_timeouts).

Patches 8-10 simplify the parameters to the build_and_send_cmd()
function.

The remaining patches are mostly just code reorg.

I have only compile tested these changes.
