Change since v3:
	PATCH 2/14	remove hunk belonging to PATCH 3/14

	PATCH 3/14	create a lib/ for common code and lib32/ lib64/

	PATCH 4/14	add setupc_64, for now setup_c() only memset bss

	PATCH 12/14	use default memory layout, chance TEXT_BASE address to let
			malloc space below

Change since v2:
	PATCH 1/14	add PHYS_ADDR_T_64BIT config

	PATCH 3/14	remove modules.c and clean atags functions in armlinux.c,
			and fix also parameters passed to linux kernel.

	PATCH 12/14	move lowlevel file from mach-qemu/ to boards/ (like others boards)
			split dram and flash init
			increase dram/flash size

	PATCH 13/14	new patch, in case of armv8, swab need to be done on 32-bit wide register
			otherwise swapping the value: "0xAAAABBBB" will become "0xAAAABBBB00000000"
			and see as a null value in uint32_t variable.

	PATCH 14/14	new patch, add define to handle arm64 uimage format


Change since v1:
	PATCH 2/12:	remove hunk which belongs to patch adding mach-qemu

	PATCH 3/12:	remove unused files

	PATCH 4/12:	create lowlevel64

	PATCH 11/12:	create pgtables64 (nothing in common with the arm32 version)

	PATCH 12/12:	rename "mach-virt" => "mach-qemu"
			rename board "qemu_virt64"
			remove board env files


Hello,

This patch series introduces a basic support for arm64.

The arm64 code is merged in the current arch/arm directory.
I try to be iterative in the merge process, and find correct solutions
to handle both architecture at some places.

I test the patch series by compiling arm64 virt machine and arm32 vexpress-a9 and test it
in qemu, everything seems to work.

Thanks,
Raphaël
