docs: document OpenWrt cfg80211 backport builds

27af5ad added the CFG80211_VERSION make variable for OpenWrt builds that
use a newer mac80211 backport than the target kernel, but it is only
described in a Makefile comment. Document how to pass it from an OpenWrt
package Makefile, link the notes from the installation steps, and add
the build script and the kernel/backports combinations verified for
issue #94.

 # AIC8800 Linux Wi-Fi and Bluetooth Driver
-This driver is for the AIC8800D80 chipset, supported by devices such as the Tenda U11 and AX913B.
+This driver supports AIC8800-family chipsets used by devices such as the Tenda U11, AX913B, and TP-Link Archer TX1U Nano.
 
-> [!IMPORTANT]
-> **Choose the branch for your hardware revision before installing.** If the
-> driver log reports `chip_id=7, chip_mcu_id=1` on an AIC8800D80 or
-> AIC8800DC/DW device, use the
-> [`legacy-mcu1`](https://github.com/shenmintao/aic8800d80/tree/legacy-mcu1)
-> branch. It contains the matched legacy firmware and loader profile required
-> to avoid the deterministic firmware upload timeout at `0x170400`. Use
-> `main` when `chip_mcu_id=0` or when the MCU revision is unknown.

+> loader profiles for the D80 upload-limit failure validated in
+> [issue #58](https://github.com/shenmintao/aic8800d80/issues/58) and the DC/DW
+> V5 main-application timeout validated in
+> [issue #71](https://github.com/shenmintao/aic8800d80/issues/71). Use
+> [`main`](https://github.com/shenmintao/aic8800d80/tree/main) for newer

+> [D80](tests/issue58-mcu1-legacy-fw/README.md) and
+> [DC/DW](tests/issue71-mcu1-v3-profile/README.md) support notes before installing.

 Added support for devices with Vendor ID 368B (tested).
 
 Tested on Linux kernel 6.16 with Ubuntu 25.04 and 6.1.0.27 with Debian 12.
 
-> [!NOTE]
-> **Maintained branches:** This repository now maintains two hardware branches:

 The same driver supports Wi-Fi-only adapters and Wi-Fi/Bluetooth combo
 adapters. On combo devices, `aic_load_fw` uploads the AIC firmware and the
 standard Linux `btusb` driver handles the Bluetooth HCI interface. The obsolete

 ### Disclaimer
 I did not develop this software, The code is sourced from the Tenda U11 driver. I only made some modifications to the code to adapt it to newer kernel versions. Apart from compilation issues, I am unable to address other problems.

+# AIC8800D80 legacy MCU revision 1 support
+
+The `legacy-mcu1` branch is the maintained compatibility profile for the older
+AIC8800D80 MCU revision tracked in
+[issue #58](https://github.com/shenmintao/aic8800d80/issues/58), with related
+reports in issues #14, #64, and #65. It is intended only for devices that log:
+
+```text
+chip_id=7, chip_mcu_id=1
+```
+
+Affected adapters have been observed entering through `a69c:572f` or a similar
+mass-storage ID, changing to `a69c:8d80` for firmware loading, and failing when
+the SDK V5 FMAC upload reaches address `0x170400`.
+
+## Root cause
+
+The affected MCU revision cannot accept the complete SDK V5 FMAC image in its
+available upload window. With an upload base of `0x120000`, the deterministic
+failure at `0x170400` gives a limit of about `0x50400` (328,704) bytes.
+
+| Firmware | Size | End address (exclusive) | Relative to `0x170400` |
+| --- | ---: | ---: | ---: |
+| SDK V5 FMAC on `main` | 358,072 bytes | `0x1776B8` | 29,368 bytes over |
+| SDK V3 FMAC on this branch | 327,037 bytes | `0x16FD7D` | 1,667 bytes free |
+
+Replacing only the FMAC image is not sufficient. Earlier mixed-firmware tests
+could enumerate but failed to provide a usable radio. This branch therefore
+uses the complete matching AIC8800D80 firmware set from Radxa SDK V3, fixed at
+upstream commit
+[`254d47e6a131dbed5ba32131972f4719f3e1c7fe`](https://github.com/radxa-pkg/aic8800/commit/254d47e6a131dbed5ba32131972f4719f3e1c7fe),
+together with its matching FMAC patch table and fixed patch-buffer layout.
+
+For `chip_mcu_id=1`, the loader also reads register `0x40100020`, sets bit 0,
+and writes it back before firmware upload. This is the MCU1 Bluetooth cache fix
+identified in [PR #35](https://github.com/shenmintao/aic8800d80/pull/35).
+Bluetooth continues to use the kernel's standard `btusb` driver; this branch
+does not contain or install `aic_btusb`.
+
+Firmware and loader paths for D80N, D80X2, and other variants are unchanged.
+The same branch now also carries the separately validated legacy DC/DW profile
+documented in the [issue #71 support notes](../issue71-mcu1-v3-profile/README.md).
+
+## Hardware validation
+
+The final profile was validated on a Steren COM-8231+ reporting
+`chip_id=7, chip_mcu_id=1`. Test commit
+[`027a7a8`](https://github.com/shenmintao/aic8800d80/commit/027a7a8)
+demonstrated all of the following:
+
+- the 327,037-byte FMAC uploads completely without `cmd timed-out` or
+  `bin upload fail: 170400`;
+- the adapter completes `a69c:572f -> a69c:8d80 -> a69c:8d81` enumeration;
+- 2.4 GHz and 5 GHz Wi-Fi scan, association, DHCP, and traffic work;
+- USB interfaces 0 and 1 bind to system `btusb`, while interface 2 binds to
+  `aic8800_fdrv`;
+- the earlier HCI Reset timeout `Opcode 0x0c03 failed: -110` is gone;
+- Bluetooth scan and a real connection both succeed.
+
+## Install
+
+From an existing clone:
+
+```bash
+git fetch origin
+git switch legacy-mcu1
+git pull --ff-only
+sudo ./install.sh
+sudo reboot
+```
+
+The installer replaces the installed AIC firmware. Switching Git branches
+without rerunning `install.sh` does not change the active firmware.
+
+The expected V3 FMAC can be confirmed with:
+
+```bash
+stat -c '%s bytes' /lib/firmware/aic8800D80/fmacfw_8800d80_u02.bin
+sha256sum /lib/firmware/aic8800D80/fmacfw_8800d80_u02.bin
+```
+
+Expected output:
+
+```text
+327037 bytes
+1ec680c2b63dcaa0e5d33c5fb6d1857d030f8145c05c385e243760388a61a0da
+```
+
+## Verify
+
+After reboot or a physical disconnect/reconnect, check the complete device:
+
+```bash
+sudo dmesg | grep -iE 'AIC8800D80|chip_id|chip_mcu_id|fmacfw|bin upload|cmd timed-out|Bluetooth|0x0c03|error -110'
+lsusb -t
+iw dev
+bluetoothctl list
+```
+
+The initialization log should contain:
+
+```text
+AIC8800D80 legacy: using Radxa SDK V3 loader profile
+AIC8800D80 MCU1: enabled Bluetooth cache fix
+```
+
+`lsusb -t` should show Bluetooth interfaces using `btusb` and the Wi-Fi
+interface using `aic8800_fdrv`. Verify traffic through the AIC network interface
+rather than an onboard Wi-Fi adapter or phone/RNDIS connection.
+
+## Return to current firmware
+
+Newer `chip_mcu_id=0` hardware should use `main`. Reinstall after switching so
+that the V5 firmware is restored under `/lib/firmware`:
+
+```bash
+git switch main
+git pull --ff-only
+sudo ./install.sh
+sudo reboot
+```

+# AIC8800DC/DW legacy MCU revision 1 support
+
+The `legacy-mcu1` branch is the maintained compatibility profile for older
+AIC8800DC/DW devices tracked in
+[issue #71](https://github.com/shenmintao/aic8800d80/issues/71). It follows the
+same method as the successful issue #58 D80 profile: use a complete, matched
+legacy firmware and loader rather than mixing firmware generations.
+
+The branch keeps the current USB transport, cfg80211 integration, device IDs,
+DKMS installer, and modern-kernel compatibility. For AIC8800DC/DW it restores
+the complete firmware directory and matching loader from immediately before
+SDK V5 commit `d66e5cb`. That loader includes the MCU1 cache fix and flash DPD
+validation used by the reporter's previously working driver.
+
+The first issue #71 test proved that the DPD result stored in flash was valid,
+but the V5 main application still timed out at `DBG_START_APP_REQ`. Test commit
+[`dbfbfa0`](https://github.com/shenmintao/aic8800d80/commit/dbfbfa0) restored the
+complete profile matching the reporter's known-good firmware hashes, after
+which the reporter confirmed that the TX1U Nano worked.
+
+## Install
+
+```bash
+git fetch origin
+git switch legacy-mcu1
+git pull --ff-only
+sudo ./install.sh
+sudo poweroff
+```
+
+After shutdown, unplug the TX1U Nano or remove host power for at least 10
+seconds before reconnecting and booting.
+
+## Verify
+
+```bash
+git rev-parse --short HEAD

+```
+
+Expected firmware values and log markers include:
+
+```text

+```
+
+There should be no command timeout, `err_lmac_reqs`, or failed USB probe after
+the main application starts.
+
+Confirm scanning, association, DHCP, gateway and Internet reachability, real
+traffic, and clean initialization after a USB unplug/replug cycle.
+
+## Roll back
+
+```bash
+git switch main
+git pull --ff-only
+sudo ./install.sh
+sudo poweroff
+```
+
+Cold-power-cycle the adapter again before booting the rollback result.
