This is the entry point of the uImage.
You can find it by
objdump vmlinux -x | grep "start address"
where, vmlinux is the image from which uImage was built.

start address = 0xC0008000 . but when we are in uboot, we have physical address, no mmu on.
here,  bootm takes physical address of sdram. So, can i load to any address and boot  ?

You can use any "Physical address" except the address range in which u-boot is running.
And one more requirement is: there should be enough memory space from that address, so that it can accommodate whole "uImage".

Hope this helps,
