[ECOS] -- please someone respond -- S3c2410x (ARM920T) HAL port

[Michael Anburaj]

No one responded to my previous emails. One way it's good; I getting to know 
ecos/Reboot underlying code much more elaborately.

The problem I was seeing may be attributed to this (not very sure):
The timer (RTC or tick) interrupt is not happening at all.

Questions:
1.	Is this (ISR) needed for proper operation of Redboot (for example for 
dispatching the gdb command like, “continue”)?
2.	The reason why the interrupt were not happening was, the I bit in CPSR 
never got cleared (IRQs enabled). The document “hal-exception-handling.html” 
in its very 1st point says about interrupts being disabled before starting 
anything. But never mentioned when its supposed to be turned ON. Someone 
familiar with the ARM ports; can you tell me where exactly the I bit in CPSR 
is cleared; this will defiantly make my job easier.

Thanks & Cheers,
-Mike.
