hi;
armel arm little endian
armhf arm hard floating
As i know (not sure), hard floating must be supported by arm cpu version which you use. A soft floating executable can run on hf OS. hf helps to speed up some processes, since it uses hardware support of cpu to perform floating point operations.
Endiannes is related to OS, little endian executable can run on big endian and vice versa...

Have a look here
