35	Amber25 improvements: Use 128-bit wishbone bus, instead of 32-bit to reduce cache miss fetch times Use a fast barrel shifter for shifts between 0 and 4 to improve timing Use a 2 cycle full barrel shifter for complex shifts	csantifort	4747d 18h	/amber/trunk/hw/vlog/amber25/a25_dcache.v
17	amber25 core bug fix. The return address for irq interrupts was off by 4 bytes when the interrupt occurred during a stm instruction with the following instruction having some register conflicts.
