[PATCH v2] Move brcm80211 to mainline

[Henry Ptasinski]

With the latest series of cleanup patches merged in by Greg KH, I'd like to
once again propose moving brcm80211 out of staging and into mainline.

I've put together a patch to add a copy of the current sources from
staging-next into wireless-testing:drivers/net/wireless/brcm80211.

The patch is somewhat large, so I've posted the patch at:

http://linuxwireless.org/en/users/Drivers/brcm80211?action=AttachFile&do=get&target=0001-wireless-testing-add-brcm80211.patch

Changes from the previous version:

V2:
- Resolve checkpatch issues
- Fix issues on big-endian platforms (MIPS BE, PPC, and SPARC)
- Cleanup architecture-specific code
- Fix power save, locking, and scan issues in brcmfmac
- Elimimnate 'void *' casts in brcmsmac
- Fix entry for brcm80211 drivers in drivers/net/wireless/Kconfig
- Use cordic and crc8 kernel library functions
- General code cleanup, restructuring, and dead code removal

The only difference between these sources and the ones in staging-next are:
	- necessary Kconfig and Makefile adjustments for the new driver location
	- one cleanup of a checkpatch warning (as indicated below)

The brcmsmac driver has been verified to work on x86 (both 32- and 64-bit), PPC
(64-bit), SPARC, MIPS BE, and ARM.  The brcmfmac driver has been verified to
work on x86 32-bit and ARM (additional testing is in progress, but getting a
working sdio controller on some of the other platforms has been challenging).

The drivers compile cleanly for x86 (32- and 64-bit), PPC (32- and 64-bit),
SPAR, MIPS BE, MIPS LE, and ARM.

Thanks,
