* MIPS: BCM47xx: Make serial explicitly non-modularPaul Gortmaker2016-10-041-7/+4
| | | | | | | | | | | | | | | | | | | | | | The Makefile entry controlling compilation of this code is "obj-y" meaning that it currently is not being built as a module by anyone. Lets remove the couple traces of modular infrastructure use, so that when reading the driver there is no doubt it is builtin-only. Since module_init translates to device_initcall in the non-modular case, the init ordering remains unchanged with this commit. We also delete the MODULE_LICENSE tag etc. since all that information was (or is now) contained at the top of the file in the comments.

* MIPS: BCM47xx: Move SPROM driver to drivers/firmware/Rafał Miłecki2016-05-134-729/+2
| | | | | | | | | | | | | | | | | Broadcom ARM home routers store SPROM content in NVRAM just like MIPS ones. To share SPROM code we need to move it out of arch/mips/ to some common place. We already have bcm47xx_nvram in firmware path and SPROM should fit there as well. This driver is responsible for parsing SoC configuration data into a struct shared between ssb and bcma buses. This was tested with BCM4706 & BCM5357C0 (BCM47XX) and BCM4708A0 (ARCH_BCM_5301X).

| * MIPS: BCM47xx: Support SPROM prefixes on other platformsRafał Miłecki2016-01-201-3/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | BCM47XX platform has specific PCI setup because all buses share the same domain. It's different e.g. on ARM ARCH_BCM_5301X where each PCI bus gets its own domain (they are handled by iProc PCIe controller driver). As we want to make SPROM driver more generic, let's add an exception for BCM47xx. It was tested on BCM4706 (MIPS) and BCM4708A0 (ARM).

* | ssb: pick SoC invariants code from MIPS BCM47xx archRafał Miłecki2015-12-161-38/+1
|/ | | | | | | | | | | | | There is code in ssb fetching "invariants" that is basically a set of board specific data. Every host requires its own implementation of reading function. In ssb we have support for PCI, PCMCIA & SDIO. For some (historical?) reason code reading "invariants" for SoC was placed in arch code and provided by a callback. This is not needed nowadays, so lets move that into ssb. This way we keep all "invariants" functions in a single module making code cleaner.

| | | | | | | | | | | | | | | | | | | | | | | | | | | After Broadcom switched from MIPS to ARM for their home routers we need to have NVRAM driver in some common place (not arch/mips/). As explained in Kconfig, this driver is responsible for parsing SoC configuration data that is passed to the kernel in flash from the bootloader firmware called "CFE". We were thinking about putting it in bus directory, however there are two possible buses for MIPS: drivers/ssb/ and drivers/bcma/. So this won't fit there and this is why I would like to move this driver to the drivers/firmware/.

* | MIPS: BCM47xx: Add generic function filling SPROM entriesRafał Miłecki2015-04-021-3/+29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Handling many SPROM revisions became messy, we have tons of functions specific to various revision groups which are quite hard to track. For years there is yet another revision 11 asking for support, but adding it in current the form would make things even worse. To resolve this problem let's add new function with table-like entries that will contain revision bitmask for every SPROM variable.

* | MIPS: BCM47XX: Increase NVRAM buffer size to 64 KiBRafał Miłecki2015-04-021-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | For years Broadcom devices use 64 KiB NVRAM partition size and some of them indeed have it filled in more than 50%. This change allows reading whole NVRAM e.g. on Netgear WNDR4500 and Netgear R8000.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There are two reasons for having this header in the common place: 1) Simplifying drivers that read NVRAM entries. We will be able to safely call bcm47xx_nvram_* functions without #ifdef-s. 2) Getting NVRAM driver out of MIPS arch code. This is needed to support BCM5301X arch which also requires this NVRAM driver. Patch for that will follow once we get is reviewed.

Linville says: ==================== pull request: wireless-next 2014-09-22 Please pull this batch of updates intended for the 3.18 stream... For the mac80211 bits, Johannes says: "This time, I have some rate minstrel improvements, support for a very small feature from CCX that Steinar reverse-engineered, dynamic ACK timeout support, a number of changes for TDLS, early support for radio resource measurement and many fixes. Also, I'm changing a number of places to clear key memory when it's freed and Intel claims copyright for code they developed." For the bluetooth bits, Johan says: "Here are some more patches intended for 3.18. Most of them are cleanups or fixes for SMP. The only exception is a fix for BR/EDR L2CAP fixed channels which should now work better together with the L2CAP information request procedure." For the iwlwifi bits, Emmanuel says: "I fix here dvm which was broken by my last pull request. Arik continues to work on TDLS and Luca solved a few issues in CT-Kill. Eyal keeps digging into rate scaling code, more to come soon. Besides this, nothing really special here." Beyond that, there are the usual big batches of updates to ath9k, b43, mwifiex, and wil6210 as well as a handful of other bits here and there. Also, rtlwifi gets some btcoexist attention from Larry. Please let me know if there are problems! ==================== Had to adjust the wil6210 code to comply with Joe Perches's recent change in net-next to make the netdev_*() routines return void instead of 'int'.
