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".
I think also need change the arch/XXX/boot/Makfile
LOADADDR=0xADDRESS
must the same in the uImage.
Hope this helps,
Jigar
