I cannot find the reference to the SystemReady Security Interface Extension or the documentation to cover the SIE, where do I find the documentation or the functionality to cover the comlpiance testing of the firmware security
The SystemReady tests to validate if the firmware meets the requirements specified by the Arm Base Boot Security Requirements specification (BBSR) remain available. These are now called BBSR tests, for clarity of naming, as they test for compliance to this specification. The BBSR ACS is fully integrated into the SystemReady band and SystemReady-devicetree band ACS prebuilt images.For further details on BBSR ACS, please refer to the BBSR ACS Verification Guide and the BBSR and Security Interface Testing FAQ section .
