BKK19-215 TPM in TEE
In this talk we are going to look into what it means to run a TEE in a TPM and answer questions like, what are the benefits and what the trade-offs when you are running a software based TPM in a TEE as a firmware TPM. For the second part of the talk we intend to have a more open discussion with the audience, where we want to discuss use cases and what kind changes that are necessary in boot components to be able talk to software based TPM instead of a real TPM.

BKK19-513 TF-A: Dynamic Configuration and PIE support
This is a presentation on Dynamic Configuration and the associated Position Independent Executable Support (PIE) in Trusted Firmware-A (TF-A).

SFO17 had a BoF session (by Dan Handley) to discuss the implementation plan for dynamic configuration in firmware. General agreement was that this is a good feature to do and some of the envisaged use-cases were: 
* Dynamic config of secure firmware features
* Dynamic firmware config using hardware configuration, security policies
* Modification of hardware configuration as seen by other software
* Centralized static firmware configuration etc

The presentation will focus on the implementation of dynamic configuration and how it can be utilized by TF-A partners. Some illustrations wherein ARM platforms dynamically configure the firmware for functionality and memory savings will also be provided.

Position Independent Executable (PIE) support for TF-A has been a long pending request from TF-A partners. The presentation will describe the technical details on how this feature was implemented in AArch64 version of TF-A. It will also cover some limitations of the implemented `dynamic relocation fixup` code.
