This default-enables the devices found on the APQ8060 DragonBoard
in the qcom_defconfig:

- EBI2 bus
- SMSC911x ethernet
- LEDs class and PM8058 LEDs driver, trigger and heartbeat
  trigger (so we get heartbeat on the board by default)
- IIO framework, including the HRTimer trigger, KXSD9
  accelerometer, MPU3050 gyroscope, AK8975 magnetometer and
  BMP085 pressure sensor

This brings up a point of discussion.  Do we even need the qcom_defconfig any
more?  Is everyone comfortable with using the multi_v7_defconfig?

Aside from size of the image, i can't think of any other reason to keep around
the separate qcom file.


Regards,
Andy

I think having one specialized defconfig for the platform is helpful for
the build/boot testing, e.g. it can show whether a boot failure with
multi_v7_defconfig is the result of a qcom-specific change, or a side-effect
of something that was done on another platform.

We recently killed of the Broadcom defconfig file that actually
contained some very different platforms that had not much in common
besides the company name.

I think my preference is to keep it, but if Andy wants it removed
and nobody complains, that's fine too.

Hi all,

In fact, as far as I remember the multi_v7 did not fit on the MDM9615
due to it's limited memory available to Linux.

This was mainly a user poll.  We'll keep it in as there is at least one user who
cannot use the multiv7 due to size.  That alone is enough to keep it around.

Linus, I'll add this to my pull list.
