Memory-Mapped I/O (MMIO) uses → 90% 2e evidence

Static MMIO read patching modifies specific MMIO read responses to control firmware execution paths.

Aurora-Fuzz ← implements 90% 1e evidence

Aurora-Fuzz adds static/constant MMIO reads in the bootloader to speed up path to user code.

UICR uses → 90% 1e evidence

Static MMIO read patching was applied to the UICR read to control the instruction pointer.
