Hi,
Thank you for your prompt response -- I really appreciate it.

What I meant was, what was the basis for the implementation of
platform_device and platform_init functions in 2.6?
By my understanding the way it worked in 2.4 was by the device probing
functions that would allocate memory, io ports etc..
m working on making the changes you suggested --
without the addition of the platform_device and other structures, the
serial console is never detected -- I never get a msg at boot time that
reads
serial8250: ttyS0 at I/O 0x3f8 (irq = whatever) is a 16550A
so I think i might need these routines
Also, the Southbridge interrupts are assigned interrupt number:
AU1000_GPIO_0..and I have included this as below:

Thanks again!
