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).

remove IAR toolchain support from make build system

2026-04-06T04:17:34Z

IAR is only supported with CMake. Remove all IAR-specific references from the Make build system including toolchain files, SRC_S_IAR, LD_FILE_IAR variables, and IAR toolchain detection. Also fix GET_SECTOR_COUNT truncation in msc_file_explorer and broken formatting in stm32f7 board_uart_write. Co-Authored-By: Claude Opus 4.6 (1M context)

implement board_uart_read()/write() as non-blocking for all families
