[yocto] Suspicious warnings while beta testing yocto 1.2

[Andrea Galbusera]

While beta testing yocto 1.2 I'm building for beagleboard with:

OE Build Configuration:
BB_VERSION        = "1.15.1"
TARGET_ARCH       = "arm"
TARGET_OS         = "linux-gnueabi"
MACHINE           = "beagleboard"
DISTRO            = "poky"
DISTRO_VERSION    = "1.1+snapshot-20120330"
TUNE_FEATURES     = "armv7a vfp neon cortexa8"
TARGET_FPU        = "vfp-neon"
meta
meta-yocto        = "<unknown>:<unknown>"

I see warnings complaining that some options set by the BSP are not
valid for the kernel being built. This is the first time I noticed and
it's confusing me. After some search I find a past conversation where
it was suggested that warnings like this for a Yocto maintained BSP
should be considered bugs. Can anyone explain this? Build is
completing successfully. Not yet tested the kernel on actual hardware.
Later I will see if something similar also happens in edison not.

Here is the log:

This BSP sets 15 invalid/obsolete kernel options.
These config options are not offered anywhere within this kernel.
The full list can be found in your workspace at:

This BSP sets 50 kernel options that are possibly non-hardware related.

WARNING: There were 12 hardware options requested that do not
         have a corresponding value present in the final ".config" file.
         This probably means you aren't getting the config you wanted.

Waiting a second to make sure you get a chance to see this...

If useful I can provide the list of options as per given log files.
