Low-level JTAG primitives operating directly on jc->io_functions (single-device chain assumed), independent of jtag_core: - bscan_set_ir - bscan_shift_dr (TDI/TDO, LSB-first packing) - bscan_idle_cycles High-level operations driven by an fpga_target descriptor: - bscan_load_bitstream: JPROGRAM -> CFG_IN -> shift (bit-reversed for Xilinx) -> JSTART -> idle -> BYPASS - bscan_load_bitstream_file: parses the Xilinx .bit container header (sections a/b/c/d/e), falls back to raw .bin bscan_spi_xfer is stubbed: the quartiq jtagspi protocol details will be wired once we have a proxy .bit to validate against (OpenOCD src/flash/nor/jtagspi.c is the host-side reference). Three new script commands: - bscan_set_ir <opcode_hex> <ir_length> - bscan_shift_dr <nbits> (writes zeros, prints captured TDO) - bscan_load_bitstream <device> <path> The sanity check for a healthy primitive on KU15P: jtag_init_scan; bscan_set_ir 9 6; bscan_shift_dr 32 -> 04 A5 60 93 Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
