Subject: [RFC PATCH 15/18] ARM: LPAE: use phys_addr_t for physical start
address in early_mem
From: Will Deacon <will.deacon@....com>
The physical start address of memory may be > 4GB and therefore
unrepresentable using an unsigned long.
This patch changes early_mem and arm_add_memory to use phys_addr_t
instead of unsigned long for the start address.
