We're trying to limit the number of options in each category, and given
there already is a wifi mediatek entry above, can we just make it install
all the mediatek wifi firmwares?

You'll need to:

  - rename the option to BR2_PACKAGE_LINUX_FIRMWARE_MEDIATEK_WIFI_MT7xxx;
    note that I added 'WIfI' in the option name, because we can forsee
    we'll have the same issue with BT firmwares, as they too are named
    mt7*;

  - add the old BR2_PACKAGE_LINUX_FIRMWARE_MEDIATEK_MT7601U option to
    Config.in.legacy, and select the new one;

  - use the new option in linux-firmware.mk to install all the WiFi
    firmware blobs.

Thanks! :-)

Regards,
Yann E. MORIN.

Hello,

I'm not sure I agree here. For other devices, we have a separate
option for each device. In addition, when you have a given WiFi device
in a system, you most likely only have this one, so the need for
installing one specific firmware is kind of the normal situationo.

If you have a WiFi/BT combo chip, it's pretty likely that you will want
to install both the WiFi and BT firmwares, so having a single option
for both doesn't look that crazy.

Best regards,

Thomas

(I probably should have waited before writing a patch doing exactly
that, hopefully i didn't tested it

I will just mention that "all the mediatek firmwares" also include more
files in linux-firmware's mediatek/ directory. But the situation there
is more complicated. the mt76/btmtk drivers are still under active
development, and they will stop using some firmware files.)

Well, currently the menuconfig for bluetooth and wifi are splitted.

And in this case, there is no firmware that is specific to a WiFi/BT
combo chip. The mt7662.bin file is used by both wifi and wifi/bt combos
and so is mt7650.bin for bt and wifi/bt.

Applied to master, thanks.
