orange-pi-zero: misc updates

Hi all,

This is the second iteration of the patchset which aimes at enabling WiFi on orange-pi-zero board right out-of-the-box. The first approach suggested to pull xr819 WiFi chip firmware from armbian repositories.

Meanwhile it turned out that Armbian project created a separate github repository to keep firmware binary blobs for all their supported boards. Reviewers (Peter Korsgaard and Yann E. Morin) suggested to use new Armbian firmware repository and organize access to firmware files in a similar way to what linux-firmware does.

Regards,
Sergey

This package enables access to firmware blobs from Armbian firmware
repository: https://github.com/armbian/firmware

That repository contains multiple firmware blobs grouped by vendor. For the sake of convenience each group can be independently selected using Kconfig options. This commit enables the following options:
- firmware blobs for XR819 SDIO WiFi chip
- firmware blobs for AP6212 WiFi/BT combo

Armbian firmware repository does not include any specific licenses. Most part of those firmware blobs belongs to various Android/Linux SDK packages provided by board vendors. As a result, this package makes use of the following conservative approach for all the selected firmware binaries:
FIRMWARE_LICENSE = PROPRIETARY
FIRMWARE_REDISTRIBUTE = NO

Make WiFi work out of the box on orange-pi-zero:
- add xr819 firmware to image
- add mdev for module autoloading

It would be good if you update or write some readme on board dir, about how to test wifi

thanks!

Well, when all the ingridients are enabled (wireless core drivers, xradio driver, xr819 firmware, and mdev), all the needed kernel modules are autoloaded on boot and wlan0 interface becomes available. That was the purpose of the patchset: to enable WiFi right after boot w/o any additional efforts like loading modules manually or looking for firmware and uploading it to the board.

All you need to do after boot is to start wpa_supplicant with proper config, or perform scan or any other operations using iw tool. However I don't think it makes sense to describe WiFi STA/AP setup in the board readme.txt. There are plenty of good sources for that, e.g. wireless.wiki.kernel.org.
