Update CYW43455 fw to 7.45.234

[pinkforest]

Undergoing validation tests. Seems we got one freeze already but might be red herring.

Bumping up to 7.45.234 Official Cypress firmware

dmesg changes brcmf_c_preinit_dcmds using brcm/brcmfmac43455-sdio for chip BCM4345/6

Jan  4 2021 19:56:29 version 7.45.229 (617f1f5 CY) FWID 01-2dbd9d2e
Apr 15 2021 03:03:20 version 7.45.234 (4ca95bb CY) FWID 01-996384e2

Affected

• brcm/brcmfmac43455-sdio for chip BCM4345/6 Power mgmt Issue #18
• Raspberry Pi 3 used to support 32 WiFi connections but is now limited to 10. RPi 3 B+ and RPi 4 are now limited to ~4 [replacing Raspbian with Ubuntu 19.10.1 increases this to 32; what does Ubuntu 20.04 offer?] iiab/iiab#823 (comment)

Probably need to check not missing anything crucial @ drivers/net/wireless/broadcom/brcm80211/brcmfmac ?

I have a Pi-tailored .234 and a new CLM blob to test. It will probably be merged this week.

Could you give it out to test? I have few guinea pigs who are getting freezes with various APs and setups. I guessed there might be some special version.. confusingly Cypress had put raspberrypi tag on their release so reasonable naive consumer ought to think it was compatible :)

There's a trial release here: https://drive.google.com/file/d/1kO1B8o_I2xnCfU8fUHv1VkBw--Jx6Aia/view?usp=sharing
It's actually 7.45.241, which is only two weeks old.

[pelwell]

7.45.241 firmware has been pushed to the bullseye branch (https://github.com/RPi-Distro/firmware-nonfree/tree/bullseye/debian/config/brcm80211/cypress, with symlinks from .../brcm).

[pinkforest]

@pelwell is there going to be AP+STA optimised firmware or is this the one that rules all?

[pelwell]

I haven't thought of a nice way to distribute the minimal firmware so that users can opt in, but since it is primarily aimed at distributions such as Internet in a Box it may just end up in the same directory as the regular firmware but with a different name. In the meantime, you can down it here: https://drive.google.com/file/d/19lAnkfe1xLrs0b0npmhwNcxcBl9kxnKJ/view?usp=sharing

@pelwell

This pull request is titled, Update CYW43455 fw to 7.45.234. Why did you push 7.45.231?

There are many reports that 7.45.231 does not support WPA3-SAE WiFi but 7.45.234 does support. How do we get 7.45.234 for WPA3-SAE?
