* wl12xx: use two MAC addresses based on the NVS or from fuse ROMLuciano Coelho2012-02-151-7/+7
| | | | | | | | | | | | | | | | | | | | | Add support for two MAC addresses. If the NVS has a valid MAC address, that takes precedence and we use two sequential address starting from the one specified. If the NVS doesn't contain a valid MAC address (ie. if it is set to 00:00:00:00:00:00), we check if the HW PG version in use has the BD_ADDR written in the fuse ROM. If it does, we read it and derive the two subsequent addresses for WLAN. During production, 3 addresses are reserved per device. The first for Bluetooth (burnt in the fuse ROM) and the following two for WLAN. This patch has some code by Igal and Arik (squashed from internal patches).

* wl12xx: read chip ID and HW PG version during probeLuciano Coelho2012-02-151-15/+0
| | | | | | | | | | | | In order to read the MAC addresses from the fuse ROM, we need to know the chip ID and the HW PG version. We need to know the MAC address during probe, because that's when we register our HW with mac80211. To prepare for that, this patch reads the chip ID and HW PG version during probe instead of doing it at boot time. We power the chip on briefly in order to do that.

* wl12xx: move partition table definition to io.cLuciano Coelho2012-02-151-66/+7
| | | | | | | | | | | Up till now we only needed to access the partition table in boot.c. But to add support for reading the MAC address from the FUSE in testmode, we will have to change the partition in testmode.c. Thus, we move the partition table to io.c and export it via io.h. It makes more sense to have it in the io part anyway. Signed-off-by: Luciano Coelho <coelho@ti.com>

* | wl12xx: move debugging definitions to a separate fileLuciano Coelho2011-10-111-0/+1
|/ | | | | | | | | | | Separate the debugging macros and other definitions to a new debug.h file. This is be needed because the sdio and spi modules don't need to depend on the wl12xx module anymore, but still need to include wl12xx.h. Currently they do depend on it, because of the debugging global that wl12xx exports. A future patch will remove this dependency. Signed-off-by: Luciano Coelho <coelho@ti.com>

* wl12xx: Support routing FW logs to the hostIdo Yariv2011-06-271-0/+9
| | | | | | | | | | | | | | | | | | | | | | A recently added feature to the firmware enables the driver to retrieve firmware logs via the host bus (SDIO or SPI). There are two modes of operation: 1. On-demand: The FW collects its log in an internal ring buffer. This buffer can later be read, for example, upon recovery. 2. Continuous: The FW pushes the FW logs as special packets in the RX path. Reading the internal ring buffer does not involve the FW. Thus, as long as the HW is not in ELP, it should be possible to read the logs, even if the FW crashes. A sysfs binary file named "fwlog" was added to support this feature, letting a monitor process read the FW messages. The log is transferred from the FW only when available, so the reading process might block. Signed-off-by: Ido Yariv <ido@wizery.com> Signed-off-by: Luciano Coelho <coelho@ti.com>
