Dear Unnamalai Kanchi Bashyam,

I have problem uncompressing the Kernel image by u-boot. It throws the message "GUNZIP: uncompress, out-of-mem or overwrite error - must RESET board to recover resetting ...".
Which exact version of U-Boot are you running (please provide the git commit ID), and which exact board configuration?
I am working on Littleton board with PXA310 processor a and 64MB DDR SDRAM.
I haven't seen any such board supported in U-Boot yet. Please consider asking the vendor who provided the U-Boot port to you.
One hint: you may want to check to which RAM address the U-Boot image is linked to. Eventually it is sitting right in the middle of your RAM.
Best regards,
Wolfgang Denk
