[U-Boot] [PATCH] ARM: make ARMV7_LPAE select PHYS_64BIT

[Masahiro Yamada]

As you see in arch/arm/include/asm/types.h, CONFIG_PHYS_64BIT
determines the size of phys_addr_t.  The ARM Large Physical Address
Extension allows CPUs to access a physical address space larger than
4GB, so the physical address may not fit in 32bit long phys_addr_t.

I did Buildman test, but not run-time test.

Looks like bcm283x (RPI) is the only arch that selects ARMV7_LPAE,
so I hope Stephen will check this patch.
