redbear-smbusd: PCI-based AMD FCH SMBus driver for the Kerncz/CZ/Ryzen SMBus controller (1022:790b). Implements piix4 MMIO-mode port selection (rev >= 0x51), SMBus transaction protocol (Quick/Read Byte/Write Byte), and registers with i2cd as a provider (scheme:smbus). Driver-manager match via 30-platform.toml (vendor=0x1022, device=0x790B, class=0x0C, subclass=0x05). 5 host-runnable tests pass. redbear-gpio-amdptd: ACPI platform driver for the AMDIF031 Promontory GPIO controller (24 pins). PT_DIRECTION/INPUT/OUTPUT/CLOCKRATE/SYNC register model. First consumer of hwd's new ACPI platform driver spawn path (HID=AMDIF031, _CRS MMIO resource handoff). Exposes scheme:gpio with per-pin claim/release via PT_SYNC_REG. 6 host-runnable tests pass. Both added to redbear-mini.toml [packages] per first-class-citizen policy (text-only substrate).
