Subject[RFC PATCH 15/23] arm: use kconfig fragments for ARCH_PXA defconfigs (part 1)
Message-ID<sLnm3-26m-59@gated-at.bofh.it>
Replace [lpd270,lubbock,mainstone,pxa255-idp]_defconfig-s with
a Makefile target using merge_config.

The patch was verified with doing:

    $ make [lpd270,...]_defconfig
    $ make savedefconfig

and comparing resulting defconfig files (before/after the patch).

Hi Bartolomiej,

It's a bit hard to judge without any context for me, especially I'm receiving
patches 11 to 21 but not the others. I suppose the advantage of defconfig
fragments was already discussed somewhere, could you point me to that please ?

One small thing that could be improved is the "pxa_basic*" names.

I think pxa_basic1 is "pxa_refboards" or something like that, as these are the
initial reference designs as far as I know from Intel and validation vehicles
rather that form factors.

In the same way, pxa_basic2 is rather "pxa_sharpsl" as these are sharp designs.

And pxa_basic3 looks like Motorola platforms, so "pxa_motorola" perhaps ?

I noticed imote2.config ended up based on pxa_basic3, while I would have
expected it to be based on pxa_basic1 as it looks like a reference board to me
...

Cheers.

Sorry about that.

http://marc.info/?l=linux-kernel&m=148102838302106&w=2

I've put the patches on hold for now after the feedback from Olof & Arnd.
