help
If you choose "EABI" here, functions and constants required by the
ARM EABI will be built into the library. You should choose "EABI"
if your compiler uses the ARM EABI, in which case you will also
need a kernel supporting the EABI system call interface, or "OABI"
for a compiler using the old Linux ABI.

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".
