Add board preset for the Alinx AXKU095 Kintex UltraScale dev board,
using the Digilent HS2 cable (FT232H). Tested JTAG detect and SRAM
programming with IDCODE 0x23844093.
BPI (parallel CFI NOR) flash support was added in #676 for
program_bpi/write, but Xilinx::dumpFlash() only handles the XC95/XCF
and SPI (PRIMARY_FLASH/SECONDARY_FLASH) paths. On boards where
_is_bpi_board is set, --dump-flash silently falls through to the SPI
FlashInterface, producing garbage instead of reading the BPI NOR.
This adds a BPI branch mirroring the existing write path: load the
BPI JTAG bridge if needed, detect the flash, read the requested
region into the target BPI flash's buffer, and write it out.
Tested on a Kintex-7 XC7K480T board with a Micron MT28GU512AAA1EGC
BPI NOR (digilent_hs2 cable): wrote random data to a scratch flash
region with --write-flash, read it back with the patched
--dump-flash, and confirmed the two are byte-identical.
ll_write() can request more than 1.5K of data, but recv() call will
return right away as soon as one packet is received. This causes large
transfers to break as not enough data is received.
Fixed by adding rx_exact flag and enabled it for ll_write()
Tested with Zynq7010 on a slow WiFi. Before the patch all uploads were
silently failing with no error in the log.

The IS25WP256 (0x9d7019, 1.8V variant of the IS25LP256) was missing
from the database, and neither 256Mb part had its Quad Enable bit
described (status register bit 6 per the IS25LP(WP)256D datasheet),
making --enable-quad fail on these parts. Required to boot Xilinx
bitstreams generated with SPI_BUSWIDTH 4.
* OpenBSD-Patch: Added the #include <sys/socket.h> in xvc_server.cpp to allow for compilation. Added a section to the README.md.
* Moved the Note regarding OpenBSD from the README.md into the doc/guide/troubleshooting.rst.
* reverted the README.md back to its original form.
* Removed a copy&paste error in the main.cpp file. Updated the documentation on OpenBSD.
* slight change to reflect the nomenclature of modules/devices in OpenBSD.
* "Windows" is spelled with only one "o".
Do not apply the Zynq non-volatile memory restriction when only reading FPGA DNA. Allow Zynq devices to use the existing 7-series DNA read path.
Tested on xc7z010 over XVC with --read-dna.
libusb_open_device_with_vid_pid() returns the first VID:PID match, so
with two ESP32-S3 cables connected, every invocation programmed the
same board. Replace it with a libusb_get_device_list() iteration that
also honours cable.bus_addr/device_addr (already exposed as
--busdev-num) and --usb-serial-num flag that matches the device
iSerialNumber by substring (useful with MAC-derived serials).
The -d /dev/ttyACM* path could not help: that's the CDC-ACM interface
(iface 0), while JTAG is on the vendor iface 2 reached via libusb;
ttyACM numbering and libusb enumeration order are independent.
Constraint: must keep existing single-board invocations working without flag changes
Confidence: high
Scope-risk: narrow
Directive: arguments struct uses positional aggregate init at main.cpp:120; new fields must add a matching slot
Not-tested: simultaneous two-board programming on real hardware (single-board path verified to build)
