There's two related problems here. Making initrd match ${rdaddr} would
be best done by doing "initrd=${rdaddr}" here, same as whacking in the
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?
previous ${bootargs}. Second
$ grep rdaddr include/configs/ti_armv7_common.h

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
