### Steps to Reproduce

- GitHub Revision: [b5b408](https://github.com/lowRISC/opentitan/commit/b5b4087210d18e313839ed5b3043c4804d4cbb13)
- dvsim invocation command to reproduce the failure, inclusive of build and run seeds:
./util/dvsim/dvsim.py hw/top_earlgrey/dv/chip_sim_cfg.hjson -i chip_sw_pwrmgr_sleep_power_glitch_reset

### Tests with similar or related failures

- [ ] chip_sw_pwrmgr_sleep_power_glitch_reset

Start by checking commit b5b408 and reproduce with the provided dvsim command using hw/top_earlgrey/dv/chip_sim_cfg.hjson. Inspect the failure in the referenced run.log and rom_ctrl_fsm.sv:209, focusing on the SecCmCFILinear_A assertion during chip_sw_pwrmgr_sleep_power_glitch_reset. Done means identifying the regression cause and confirming the test no longer reports the assertion failure.
