- Introduced target in Makefile to run fast-flash HP Linux userspace acceptance tests with a 7200-second simulation time limit. - Updated documentation to describe the new fast-flash model and its usage in simulations. - Implemented Verilator-specific XPI core and fast flash model to handle slot-0 read operations with improved performance. - Added new tests for the XPI fast flash model to verify protocol compliance and error handling. - Enhanced existing tests to ensure proper integration of fast-flash features in the HP Linux simulation flow.
