AFIK, you can't run linux on an ARM TDMI with 64K of RAM :-) |

Using the same endianess as your bootloader will save you from byte |
| 34 |
swapping. If you can use the same endianness as the rest of your HW, |
| 35 |
it will save the byte sapping operations and may make your system faster. |

Some people prefer little endian, because other SW/ drivers has bugs on |
| 39 |
little endian machines. |

More about endianness you can probably get from googl'ing. |
