On some PAE architectures, the entire range of physical memory could reside
outside the 32-bit limit.  These systems need the ability to specify the
initrd location using 64-bit numbers.

This patch globally modifies the early_init_dt_setup_initrd_arch() function to
use 64-bit numbers instead of the current unsigned long.

S-o-B?

Sorry about that, will include in v2.

phys_initrd_start/size need to change too. Not sure about similar things
on other arches.

I've fixed phys_initrd_start (not size) in another patch, please see [1].

Does u-boot need similar fixes?

We aren't there yet :-)  We are currently running this platform without 
u-boot.
