ARM: remove sub-arch/variants selection from menuconfig
Rely on the compiler to be correctly set up to generate appropriate code for the target variant. This exposes the Thumb option, as it is no longer auto-selected. The "Use BX" no longer depends on supported CPU to be selected, so it now defaults to 'n' as it shall work by default on CPUs that do not have BX. Signed-off-by: "Yann E.

- prompt "Target Processor Type"
- default CONFIG_GENERIC_ARM
- help
- This is the processor type of your CPU. This information is used for
- optimizing purposes. To build a library that will run on all ARMCPU
- types (albeit not optimally fast), you can specify "Generic Arm" here.
- If you pick anything other than "Generic Arm", there is no guarantee
- that uClibc will even run on anything other than the selected
- processor type.
-
- Here are the settings recommended for greatest speed:
- - "Generic Arm" select this if your compiler is already setup to
- optimize things properly, or if you want to run on pretty much
- everything, or you just don't much care.
- - For anything else, pick the ARM core type that best matches the
- cpu you will be using on your device.
-
- If you don't know what to do, choose "Generic Arm".
