This is a presentation on Dynamic Configuration and the associated Position Independent Executable Support (PIE) in Trusted Firmware-A (TF-A).<br /><br />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:&nbsp;<br />* Dynamic config of secure firmware features<br />* Dynamic firmware config using hardware configuration, security policies<br />* Modification of hardware configuration as seen by other software<br />* Centralized static firmware configuration etc<br /><br />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.<br /><br />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.
