And why don't you learn the syntax and semantics of ARM assembler
before you send messages to this list?

In order to understand the interrupt related things I recommend reading
some documents about ARM architecture, your processor datasheet(s) AND
U-BOOT DOCUMENTATION. Then you will find out by yourself why it is so
difficult to understand interrupt handling on most platforms... :-) And
why don't you just hook your JTAG debugger on the interrupt entry point
and try to follow the execution flow? Then you will also notice
something very important in U-Boot...
