Subject[PATCH v2 0/2][powerpc] Export memory_limit via device tree
Date
The following series exports the linux memory_limit set by
the mem= parameter via device-tree, so that kexec-tools
can limit the crash regions to the actual memory used by
the kernel.

Change since V1:

* Added a patch to change the type of memory_limit to a
fixed size(unsigned long long) from 'phys_addr_t' (which
is 32bit on some ppc32 and 64 bit on ppc64 and some ppc32)

* Rebased the patch to use recently fixed prom_update_property()
which would add the property if it didn't exist.
