2012-03-06bcma: add support for on-chip OTP memory used for SPROM storageArend van Spriel1-1/+9
Wireless Broadcom chips can have either their SPROM data stored on either external SPROM or on-chip OTP memory. Both are accessed through the same register space. This patch adds support for the on-chip OTP memory. Tested with: BCM43224 OTP and SPROM BCM4331 SPROM BCM4313 OTP This patch is in response to linux-wireless thread [1]. [1] http://article.gmane.org/gmane.linux.kernel.wireless.general/85426 Tested-by: Saul St. John <saul.stjohn@gmail.com> Tested-by: Rafal Milecki <zajec5@gmail.com> Tested-by: Hauke Mehrtens <hauke@hauke-m.de> Cc: Larry Finger <Larry.Finger@lwfinger.net> Signed-off-by: Arend van Spriel <arend@broadcom.com> Signed-off-by: John W.

2012-03-05bcma: add support for sprom not found on the deviceHauke Mehrtens1-0/+6
On SoCs the sprom is stored in the nvram in a special partition on the flash chip. The nvram contains the sprom for the main bus, but sometimes also for a pci devices using bcma. This patch makes it possible for the arch code to register a function to fetch the needed sprom from the nvram and provide it to the bcma code.

2012-02-06bcma: add extra sprom checkHauke Mehrtens1-0/+16
This check is needed on the BCM43224 device as it says in the capabilities it has an sprom but is extra check says it has not. Signed-off-by: Hauke Mehrtens <hauke@hauke-m.de> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2012-02-06bcma: add bus num counterHauke Mehrtens1-0/+1
If we have two bcma buses on one computer the second will not work without this patch. Now each bus gets an own number. Signed-off-by: Hauke Mehrtens <hauke@hauke-m.de> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2012-02-06bcma: add PCIe host controllerHauke Mehrtens2-0/+65
Some SoCs have a PCIe host controller to make it possible to attach some other devices to it, like an other Wifi card. This code was tested with an Netgear WNDR3400 (bcm4716 based), but should work with all bcma based SoCs. Signed-off-by: Hauke Mehrtens <hauke@hauke-m.de> Signed-off-by: John W.

2012-02-06bcma: make some functions __devinitHauke Mehrtens1-1/+1
bcma_core_pci_hostmode_init() has to be in __devinit as it will call a function in that section and so all functions calling it also have to be in __devinit. Signed-off-by: Hauke Mehrtens <hauke@hauke-m.de> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2012-02-06bcma: add constants for PCI and use themHauke Mehrtens1-0/+85

2012-02-06bcma: add the core unit numberHauke Mehrtens1-0/+1

2011-12-13bcma: use static keyword for inline function declaration in bcma.hArend van Spriel1-11/+12
Just scratching an itch here, but it makes more sense to use the static keyword if you think about how the compiler treats inline functions.

2011-12-13bcma: add set/mask macros for 16-bit register accessArend van Spriel1-6/+26
The BCMA header only had definitions for 32-bit register access. Used those as a template for the 16-bit flavour. Also changed them to inline functions to be on the safe side. As offset parameter is used twice there would be a problem when used like this: bcma_set32(core, offset++, val); Reviewed-by: Pieter-Paul Giesberts <pieterpg@broadcom.com> Reviewed-by: Alwin Beukers <alwin@broadcom.com> Signed-off-by: Arend van Spriel <arend@broadcom.com> Signed-off-by: Franky Lin <frankyl@broadcom.com> Signed-off-by: John W.

2011-10-31include: convert various register fcns to macros to avoid include chainingPaul Gortmaker1-4/+3
The original implementations reference THIS_MODULE in an inline. We could include <linux/export.h>, but it is better to avoid chaining. Fortunately someone else already thought of this, and made a similar inline into a #define in <linux/device.h> for device_schedule_callback(), [see commit 523ded71de0] so follow that precedent here. Also bubble up any __must_check that were used on the prev. wrapper inline functions up one to the real __register functions, to preserve any prev. sanity checks that were used in those instances.

2011-08-08bcma: add SOC busHauke Mehrtens2-1/+20
This patch adds support for using bcma on a Broadcom SoC as the system bus. An SoC like the bcm4716 could register this bus and use it to searches for the bcma cores and register the devices on this bus. BCMA_HOSTTYPE_NONE was intended for SoCs at first but BCMA_HOSTTYPE_SOC is a better name.

2011-08-08bcma: add functions to scan cores needed on SoCsHauke Mehrtens2-0/+2
The chip common and mips core have to be setup early in the boot process to get the cpu clock. bcma_bus_early_register() gets pointers to some space to store the core data and searches for the chip common and mips core and initializes chip common. After that was done and the kernel is out of early boot we just have to run bcma_bus_register() and it will search for the other cores, initialize and register them. The cores are getting the same numbers as before.

2011-06-20bcma: clean exports of functionsRafał Miłecki1-0/+2

2011-06-03bcma: read SPROM and extract MAC from itRafał Miłecki2-0/+6
In case of BCMA cards SPROM is located in the ChipCommon core, it is not mapped as separated host window. So far we have met only SPROMs rev 8. SPROM layout seems to be the same as for SSB buses, so we decided to share SPROM struct and some defines. For now we extract MAC address only, this can be improved of course.

2011-05-10bcma: add Broadcom specific AMBA bus driverRafał Miłecki4-0/+644
Broadcom has released cards based on a new AMBA-based bus type. From a programming point of view, this new bus type differs from AMBA and does not use AMBA common registers. It also differs enough from SSB. We decided that a new bus driver is needed to keep the code clean. In its current form, the driver detects devices present on the bus and registers them in the system. It allows registering BCMA drivers for specified bus devices and provides them basic operations. The bus driver itself includes two important bus managing drivers: ChipCommon core driver and PCI(c) core driver. They are early used to allow correct initialization. Currently code is limited to supporting buses on PCI(e) devices, however the driver is designed to be used also on other hosts. The host abstraction layer is implemented and already used for PCI(e). Support for PCI(e) hosts is working and seems to be stable (access to 80211 core was tested successfully on a few devices). We can still optimize it by using some fixed windows, but this can be done later without affecting any external code. Windows are just ranges in MMIO used for accessing cores on the bus.
