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

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