This patch set the correct initrd address to much rdaddr, which used at get_fs_ramfs commad.

For keystone devices we load filesystem at ${rdaddr}, but need to pass to the kernel initrd=<${rdaddr} + 0x780000000)>, which is LPAE address.
How can I do that w/o using absolute address?

So you aren't making it match here either. Finally (and please test this..), do you _need_ to pass in the size parameter here? I'm assuming that this is _not_ a uImage'd ramdisk here but instead a raw one so we end up with the case of the kernel would know where the ramdisk starts but would assume a max size of whatever it was compiled with and then find an incomplete rootfs, right? If so then yes, that's fine, we can continue passing in (and updating in the second patch as you are) the size parameter, I just want to be sure we aren't missing out on some "new" smarts that exist in the kernel. Thanks!
You are right. That is to load a standalone file system to the ram and let kernel to know the start address.
Thanks
