But why is redboot on a PC more then 10 times faster. Is this only because of 
the faster processor? In the following example I used a 400 MHz Pentium.

Loading section .text, size 0x39525 lma 0x108000
Loading section .rodata, size 0x3d06 lma 0x141528
Loading section .data, size 0x5230 lma 0x145230
Start address 0x108000 , load size 271451
Transfer rate: 2171608 bits in <1 sec, 318 bytes/write.
