I would like to modify the uboot so that it could boot up 2.4 and 2.6 kernel without downloading the u boot again . what i know the difference
There is absolutely no need to modify U-Boot for this purpose. It can boot many different operating systems and different Linux kernel versions without any code changes.
is : 2.6 kernel know how to copy itself to memory but 2.4 do not and need bootloader to do it. Am i right ? How can i do this inorder to make it more convinent ?
No, you are wrong. There are absolutely no changes needed.
In general, do you mean both kernel should know how to copy itself to memory and the bootloader don't need to handle this ?
