Bug #245
openAdd missing Broadcom firmwares (Solidrun Hummingboard IIOT)
100%
Description
Adding these firmwares will fix these issues:

For Hummingboard IIOT based on BSP/kernel 5.15 it might use: https://github.com/SolidRun/meta-solidrun-arm-imx8/blob/kirkstone-imx8m/recipes-kernel/linux-firmware/linux-firmware_%25.bbappend
Next step is to package these firmwares + test on the board

- before on redpesk package by default (
solidrun-firmware-1.1.0-3.redpesk.bsp.hummingboard.iiot_95a64572.rpbatz.aarch64) :
[root@d0-63-b4-05-d1-23 ~]# dmesg |grep brcm
[ 8.125721] brcmfmac: brcmf_fw_alloc_request: using brcm/brcmfmac43455-sdio for chip BCM4345/6

- what I have now (
solidrun-firmware-2.0.0-1.firmwares.brcm_bb32e33e.rpbatz.aarch64) :

I have to look to regulatory.db and integrate everything in the R-Cube project
All firmwares come from Yocto SolidRun kirkstone imx8M sources (kernel 5.15) that we must update for kernel 6.6 BSP Scarthgap

For the following error, I don't know how to manage that because the package which gives the db and its signature is here...
[root@d0-63-b4-05-d1-23 ~]# dmesg |grep regulatory
[ 2.884643] cfg80211: Loading compiled-in X.509 certificates for regulatory database
[ 2.927528] platform regulatory.0: Direct firmware load for regulatory.db failed with error -2
[ 2.941858] platform regulatory.0: Falling back to sysfs fallback for: regulatory.db
[ 64.485981] cfg80211: failed to load regulatory.db
However the package is installed:
[root@d0-63-b4-05-d1-23 ~]# dnf provides /usr/lib/firmware/regulatory.db

Summary : Regulatory database for 802.11 wireless networking
Description :
The wireless-regdb package provides the regulatory rules database
used by the kernels 802.11 networking stack in order to comply
with radio frequency regulatory rules around the world.
I studied the driver code, here is the error: https://github.com/nxp-imx/linux-imx/blob/lf-5.15.y/net/wireless/reg.c#L1045
So we have not firmware loaded but it exists on the target in both paths:
[root@d0-63-b4-05-d1-23 ~]# ls -l /lib/firmware/ |grep regu
-rw-r--r-- 1 root root 3940 May 16 2024 regulatory.db
-rw-r--r-- 1 root root 1182 May 16 2024 regulatory.db.p7s
[root@d0-63-b4-05-d1-23 ~]# ls -l /usr/lib/firmware/ |grep regu
-rw-r--r-- 1 root root 3940 May 16 2024 regulatory.db
-rw-r--r-- 1 root root 1182 May 16 2024 regulatory.db.p7s
So probably it's dealing with the x.509 certificate but disabling the configuration hasn't impact (same issue):
# disable CFG80211 database verification (not needed)
CONFIG_EXPERT=y
CONFIG_CFG80211_CERTIFICATION_ONUS=y
CONFIG_CFG80211_REQUIRE_SIGNED_REGDB=n
CONFIG_CFG80211_USE_KERNEL_REGDB_KEY=n
Another try I made is to take the latest wireless-regdb here: https://git.kernel.org/pub/scm/linux/kernel/git/wens/wireless-regdb.git/tree/
But the issue is still present. Since this is not a blocking issue for WiFi operational features, maybe we'll fix that with 6.6 Kernel / redpesk corn 3.0!
