Sorry for the late reply. I was busy with another project.

I finally got linux 2.6 to boot on HITECH board. 

Thanks to John Linn for all the pointers to debug the code. I also got the
UARTLITE as console working. I had to disable several macros in
virtex_devices.c to make the kernel boot.

Now I am working on using UART16550 as console which is free at Xilinx after
registration. Thanks to Marc and Stephen for the info.
