bcma: use fallback sprom if sprom on card was not valid

2012-10-19T19:52:53+00:00

Sometimes the PCIe card indicates that it has a sprom somewhere and we
are able to read the memory region, but it is empty and not valid. In
these cases we should try to use the fallback sprom as a last chance.

This is the case for the PCIe cards in my ASUS RT-N66U (BCM4706 + 2
times BCM4331) and I have heard of someone having the same problem with
an other PCIe card connected to an other Broadcom SoC.

bcma: use custom printing functions

2012-07-09T20:36:36+00:00

Having bus number printed makes it much easier to anaylze logs on
systems with more buses. For example Netgear WNDR4500 has 3 AMBA buses
in total, which makes standard log really messy.

bcma: add constants for chip ids

2012-07-09T20:36:03+00:00

The chip IDs are used all over bcma and no constants where defined.
This patch adds the constants and makes bcma use them.

bcma: add ext PA workaround for BCM4331 and BCM43431

2012-06-04T19:26:40+00:00

MacBook Pro models with BCM4331 wireless have been found to have the ext
PA lines disabled after resuming from S3 without external power attach.
This causes them to be unable to transmit. Add a workaround to ensure
that the ext PA lines are enabled on BCM4331. Also extend all handling
of ext PA line muxing to BCM43431 as is done in the Broadcom SDK.

bcma/ssb: parse new attributes from sprom

2012-05-16T16:45:22+00:00

These newly added attributes are used by brcmsmac. Now bcma should
parse all attributes used by brcmsmac out of the sprom.

bcma: read out some additional sprom attributes

2012-05-16T16:45:21+00:00

This code is copied from the ssb sprom read code. These attributes are
partly used by b43 and brcmsmac and should also be read out on bcma
based devices.

ssb/bcma: fill attribute alpha2 from sprom

2012-05-16T16:45:21+00:00

The attribute country_code and alpha2 are two different attributes in
the sprom. country_code contains some code in an 8 bit coding and
alpha2 contains two chars with the country code. The attributes where
read out wrongly in the past and country_code is only available on
sprom version 1.

bcma: use fallback sprom if no on chip sprom is available

2012-04-16T17:32:01+00:00

bcma should check for a fallback sprom every time it can not find a
sprom on the card itself or a normal external sprom mapped into the
memory of the chip. When otp sprom support was introduced it tried to
read out the sprom from the wireless chip also if no otp sprom was
available. This caused a Data bus error in bcma_sprom_get() when
reading out the sprom for the SoC.

This fixes a regression introduced in commit:

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

This patch was tested on a Netgear WNDR3400 (Broadcom BCM4718 SoC).
