brcmfmac, BCM43241

[Jan-Oliver Kaiser <mail@janno-kaiser.de>]

Hi,

I am trying to get a BCM43241 card running on a 3.11-amd64 kernel.
[1] lists the device as supported but gives no instructions on how to
install it. I managed to extract the firmware from the git binary patch
contained in [2].

I copied the firmware to /lib/firmware/brcm/brcmfmac-sdio.bin and copied
the content of /dev/nvram to /lib/firmware/brcm/brcmfmac-sdio.txt.

Previously, `dmesg` would list error that indicated missing files.
Currently, the output is as follows:

[12865.299503] brcmfmac: brcmf_sdio_chip_drivestrengthinit: No SDIO

[12869.426308] brcmfmac: brcmf_sdbrcm_htclk: HT Avail timeout (1000000):
clkctl 0x50

I have not been able to find anything to help with debugging this.

There was some discussion in response to [2] that I don't understand. Is
there something wrong with the firmware itself?

I would be very grateful for any help. I can provide all additional
information if something is missing from this report. (I can also be
reached via IRC, 'Eruquen' on freenode)

Thanks in advance,
Jan-Oliver
