I am trying to use the initrd function of u-boot and I think I am almost there. However it does not seem that u-boot is re-locating the initrd into ram from flash. Is it supposed to do this? U-Boot is passing the address of the initrd in flash. How can I make it re-locate into ram first then pass the address to the kernel.
Here is the output.
