2012-04-10bcma: fix build error on MIPS; implicit pcibios_enable_devicePaul Gortmaker2-1/+2
The following is seen during allmodconfig builds for MIPS: drivers/bcma/driver_pci_host.c:518:2: error: implicit declaration of function 'pcibios_enable_device' [-Werror=implicit-function-declaration] cc1: some warnings being treated as errors make[3]: *** [drivers/bcma/driver_pci_host.o] Error 1 Most likey introduced by commit 49dc9577155576b10ff79f0c1486c816b01f58bf "bcma: add PCIe host controller" Add the header instead of implicitly assuming it will be present. Sounds like a good idea, but that alone doesn't fix anything. The real problem is that the Kconfig has settings related to whether PCI is possible, i.e. config BCMA_HOST_PCI_POSSIBLE bool depends on BCMA && PCI = y default y config BCMA_HOST_PCI bool "Support for BCMA on PCI-host bus" depends on BCMA_HOST_PCI_POSSIBLE ...but what is missing is that BCMA_DRIVER_PCI_HOSTMODE doesn't have any dependencies on the above.

2012-03-06bcma: add support for on-chip OTP memory used for SPROM storageArend van Spriel1-20/+106
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].

2012-03-06bcma: return error in bcma_sprom_get() when fallback failsArend van Spriel1-10/+17
When not SPROM is available a fallback mechanism is used. However, when that fails the code currently continues. This patch assures that the bcma_sprom_get() function aborts when that happens.

2012-03-05bcma: add support for sprom not found on the deviceHauke Mehrtens1-8/+69
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: don't fail for bad SPROM CRCHenrik Rydberg1-3/+1
The brcmsmac driver is now using the bcma SPROM CRC check, which does not recognize all chipsets that were functional prior to the switch. In particular, the current code bails out on odd CRC errors in recent Macbooks. This patch ignores those errors, with the argument that an unrecognized SPROM should be treated similarly to a non-existing one.

2011-08-08bcma: add functions to scan cores needed on SoCsHauke Mehrtens5-6/+152
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.
