Re: Broadcom driver in Android
Just found this in the Android's repository and think maybe this info can be useful for someone in this list: http://android.git.kernel.org/?p=platform/system/wlan/broadcom .git;a=summary .. and it's even GPL. :-) ___ Bcm43xx-dev mailing list Bcm43xx-dev@lists.berlios.de https://lists.berlios.de/mailman/listinfo/bcm43xx-dev

Though there are handlers in the code to download firmware somewhere (they end with _download_firmware), so should one believe that a firmware image could be provided?

WARNING: My knowledge on this only vague Does is support the same devices that b43(legacy) does? From what I know (and have seen by skimming thru the driver), this driver does support some kind of embedded wlan chip from broadcom. This chip is connected via sdio, and has a built in ARM7TDMI CPU alongside with RAM and (some kind of) ROM. The WLAN stack runs inside this CPU. The host communicates with this device like with an standard ethernet card (albeit with some extensions). If the device was an usb device, this would be called CDC (communcation device class), her it is called DCH (whatever...) There is a modified CDC driver in the kernel to support similar broadcom usb cards. the b43 driver does support broadcom cards without this embedded cpu (connected via PCI...) and does implement the functions of the embedded code of the embedded cards on the x86 host cpu. So this driver is orthogonal to b43 Maybe including LP-PHY? Or 802.11n devices? Is there anything in this driver we can (and need to) port to b43? ___ Bcm43xx-dev mailing list Bcm43xx-dev@lists.berlios.de https://lists.berlios.de/mailman/listinfo/bcm43xx-dev
