Starting from Bryan Larsen's patch for U-Boot 0.4.0, I started porting 
U-Boot 1.1.2 on Cogent CSB336.
The patch against current CVS is available for download here 
http://www.dave-tech.it/download/misc/up-csb336-1 (I could not attach 
because the size limit). Some clean ups are needed here and there.
I had to change the routine reset_timer_masked in cpu/mc9328/interrupts.c 
To initialize clocks and SDRAM controller I used the same values used by 
the Micromonitor bootloader the board comes with.
I also had to avoid invoking funtion SetAsynchMode() otherwise the 
processor hangs.

U-Boot seems to be stable but I could not load Linux kernel so far. I'm 
trying to start a modified version of the kernel 0.3.8 delivered by 
Motorola for the M9328MXL ADS. It seems the kernel does not like the 
parameters passed by U-Boot. Still working on it. Any advice or suggestion 
is appreciated.
