We want to remove the ARCH_MSM* configs in mach-qcom/Kconfig

I have been removing the ARCH dependencies in the Kconfig file.
Why do you have to turn it off manually ?
The background is that this is used only on some of the older
MSM SoCs, while the newer ones use the arch timer.
We decided to remove the SoC-specific top-level options from
mach-msm as they are becoming rather meaningless these days
and just a burden to maintain at the rate that new variants
get released, so being able to turn off this driver helps make
the kernel slightly smaller if you are building a kernel for
only the more recent models.
Ok, thanks for the clarification.
I don't really like this approach even if it is correct because it
breaks the current approach I am trying to make consistent across the
drivers.
I would like to have the COMPILE_TEST option available for all the
drivers and move this option under the menu config. This patch will
prevent to do this code factoring.
On the other side, this option is supposed to have a slightly smaller
kernel when it is not used. But when does it happen ? When
ARCH_MSM8X60=n and ARCH_MSM8960=n. With this patchset, I don't see the
ability to turn these SoCs off as the options are removed. So the
associated code is not removed, right ?
So why allow to turn off the timer but disallow that for the entire SoC ?
