PXA: Align stack to 8 bytes

Part of this patch is by: Mikhail Kshevetskiy.

Stack must be aligned to 8 bytes on PXA (possibly all armv5te) for LDRD/STRD
instructions. In case LDRD/STRD is issued on an unaligned address, the behaviour
is undefined.

The issue was observed when working with the NAND code, which was rendered
disfunctional. Also, the vsprintf() function had serious problems with printing
64bit wide long longs. After aligning the stack, this wrong behaviour is no
longer present.

Tested on:
Marvell Littleton PXA310 board
Toradex Colibri PXA320 board
Aeronix Zipit Z2 PXA270 handheld
Voipac PXA270 board

ARM1176: Coexist with other ARM1176 platforms

The current ARM1176 CPU specific code is too specific to the SMDK6400
architecture.  The following changes were necessary prerequisites for the
addition of other SoCs based on ARM1176.

Existing board's (SMDK6400) configuration has been modified to keep behavior
unchanged despite these changes.

1. Peripheral port remap configurability
The earlier code had hardcoded remap values specific to s3c64xx in start.S.
This change makes the peripheral port remap addresses and sizes configurable.

2. U-Boot code relocation support
Most architectures allow u-boot code to run initially at a different
address (possibly in NOR) and then get relocated to its final resting place
in RAM.  Added support for this capability in ARM1176 architecture.

3. Disable TCM if necessary
If a ROM based bootloader happened to have initialized TCM, we disable it here
to keep things sane.

4. Remove unnecessary SoC specific includes
ARM1176 code does not really need this SoC specific include.  The presence
of this include prevents builds on other ARM1176 archs.

5. Modified virt-to-phys conversion during MMU disable
The original MMU disable code masks out too many bits from the load address
when it tries to figure out the physical address of the jump target label.
Consequently, it ends up branching to the wrong address after disabling the

fdt_support: add entry for sec3.1 and fix sec3.3

Add sec3.1 h/w geometry for fdt node fixups.

Also, technically, whilst SEC v3.3 h/w honours the tls_ssl_stream descriptor
type, it lacks the ARC4 algorithm execution unit required to be able
to execute anything meaningful with it.  Change the node to agree with
the documentation that declares that the sec3.3 really doesn't have such
a descriptor type.

fsl: rename 'dma' to 'brdcfg1' in the ngPIXIS structure

The ngPIXIS is a board-specific FPGA, but the definition of the registers
is mostly consistent.  On boards where it matter, register 9 is called
'brdcfg1' instead of 'dma', so rename the variable in the ngpixis_t
definition.

This patch fixes the run-time error on div64 when built with
gcc4, which was reported by jhwu0625 on nios forum. It merges
math support from libgcc of gcc4. This patch is copied from
nios2-linux.

It works with both gcc3 and gcc4. The old mult.c, divmod.c and

nios2: fix r15 issue for gcc4

The "-ffixed-r15" option doesn't work well for gcc4. Since we
don't use gp for small data with option "-G0", we can use gp
as global data pointer. This allows compiler to use r15. It
is necessary for gcc4 to work properly.
