fix(ci_fs): address code-review findings in host/device drivers

2026-07-17T17:18:27Z

Host (hcd_ci_fs.c): - Release the speculatively-armed sibling BDT on the NAK path (IN only) as well as on completion, so a NAKed multi-packet IN no longer leaks a BDT that stays own=1 and blocks every same-direction pipe. Both paths now go through a single release_sibling_bd() helper (was a copy-pasted disarm). - Clear the ENTIRE shared BDT (both directions) on bus reset; clearing only the IN half left a stale OUT/SETUP descriptor after a disconnect mid-OUT, blocking the first control transfer on re-enumeration. - Size bda[] to span the whole BDT (2*2*4) so STAT-indexed access is within the declared array bounds (was out-of-declared-bounds, benign via union). Shared (ci_fs_type.h): - Hoist buffer_descriptor_t and the TOK_PID enum out of the device and host drivers into the shared header so the identical definitions cannot drift. Board (kinetis_k): - Drop a redundant local in board_get_unique_id. Build-verified: host + kinetis k/kl/k32l + MCX. HIL: frdm_k64f host 2/2 (cdc_msc_hid + device_info); frdm_kl25z device core suite green with the relocated definitions.

kinetis_k: non-blocking board_uart_read (RX FIFO) + SIM unique id

2026-07-17T10:26:04Z

- board_uart_read was a stub returning 0, so host examples that bridge the UART console to a CDC device (echo test) received nothing. Implement it via an RDRF-interrupt-fed tu_fifo, matching the stm32 family (non-blocking, no RX overrun). board_uart_write is already non-blocking. - implement board_get_unique_id() from the SIM 128-bit UID registers so frdm_k64f/teensy_35 report a real USB serial instead of the fixed default.

migrate NXP Kinetis khci to chipidea ci_fs driver (device + host)

2026-07-17T10:26:02Z

Complete the khci -> chipidea ci_fs migration that was started for device (commit d70403f1f "host is not yet"): - device: switch kinetis_k/kl/k32l (Makefiles + k32l CMake) to dcd_ci_fs.c - host: add hcd_ci_fs.c (port of hcd_khci.c onto ci_fs_regs_t) and switch all Kinetis families to it; remove src/portable/nxp/khci entirely - enable host examples (device_info, cdc_msc_hid) for mcu:KINETIS_K - README: merge the KL and K32L2 rows into a single "KL, K32L" ci_fs row hcd_ci_fs.c also fixes two pre-existing host bugs found via HIL on frdm_k64f (present in the old hcd_khci.c too): - data toggle was flipped on a NAK in suspend_transfer; a NAK transfers no data so the toggle must be preserved, else the retried bulk packet is silently discarded by the device (MSC CBW/CSW hang). See comment in file. - prepare_packets asserted and dropped a transfer when the single shared BDT was still owned by an in-flight transfer under concurrent activity; now it returns busy and resume_transfer defers/retries on the next SOF. HIL verified on frdm_k64f: device 13/13, host cdc_msc_hid (CDC mount + echo + MSC mount, through a hub).

lpc15, lpc40: board_get_unique_id via IAP ReadUID

2026-07-17T09:48:02Z

Real 128-bit chip UID as the board serial (IAP cmd 58, status checked against IAP_CMD_SUCCESS), replacing the shared placeholder — required for HIL board identification by serial. lpc40's lpcopen Chip_IAP_ReadUID() returns only the first UID word, hence the direct iap_entry() call. Verified on ea4088_quickstart and lpcxpresso1549: both enumerate with their chip UID and are selected by it in the HIL configs.
