[ECOS] reboot is slow

[linux.chips]

thanks for the reply

the caches are enabled (typing cache in the prompt tells me it on ). i 
am not sure where to find the memory initialization, currently looking 
for it. the cpu clock is tunable as far as i now, i can see options for 
cpu clock selections in the cdl files. how can i verify the 
initialization and cpu clock are correct??
unfortunately i could not get a source code of the stock redboot.
