bcma: fix build error on MIPS; implicit pcibios_enable_device

2012-04-10T18:13:30+00:00

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.  Add one.

bcma: add support for on-chip OTP memory used for SPROM storage

2012-03-06T20:16:18+00:00

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].

bcma: return error in bcma_sprom_get() when fallback fails

2012-03-06T20:16:18+00:00

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.

bcma: add support for sprom not found on the device

2012-03-05T20:20:50+00:00

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.

bcma: add extra sprom check

2012-02-06T19:53:06+00:00

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.

If we have two bcma buses on one computer the second will not work
without this patch. Now each bus gets an own number.
