brcmfmac43430-sdio.clm_blob needs to be diverted

[Juerg Haefliger]

A recent update of linux-firmware 'fixed' dangling symlinks and now the raspi kernel tries to load brcm/brcmfmac43430-sdio.clm_blob from the linux-firmware package but uses the FW blob brcm/brcmfmac43430-sdio.bin from the linux-firmware-raspi2 package. The two don't play well together:

$ sudo dmesg | grep brcm
[ 17.643748] brcmfmac: F1 signature read @0x18000000=0x1541a9a6

[ 18.059280] brcmfmac: brcmf_sdio_firmware_callback: brcmf_attach failed

The FW blob from linux-firmware-raspi already contains CLM data and doesn't need to load a dedicated blob. In fact it must not, so linux-firmware-raspi2 needs to divert brcm/brcmfmac43430-sdio.clm_blob from the linux-firmware package.
