+ 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" for any ARM core
+ - "arm7tdmi" an MMU-less ARM core such as those distributed
+ by Atmel, Samsung, and others.
+ - "StrongARM" for Intel's StrongARM cores, such as the
+ StrongARM 110/1100/1110.
+ - "XScale" for Intel's XScale processors
+
+ If you don't know what to do, choose "Generic Arm".
