This patch performs the following:
1) Convert the assembly code for memory and clock initialization to C code.
2) Move the memory and clock init codes from board/samsung to arch/arm
3) Creat a common lowlevel_init file across Exynos4 and Exynos5. Converted
the common lowlevel_init from assembly to C-code
4) Made spl_boot.c and tzpc_init.c common for both exynos4 and exynos5.
5) Enable CONFIG_SKIP_LOWLEVEL_INIT as stack pointer initialisation is already
done in _main.
6) exynos-uboot-spl.lds made common across SMDKV310, Origen and SMDK5250.
TEST: Tested SD-MMC boot on SMDK5250 and Origen.
Tested USB and SPI boot on SMDK5250
Compile tested for SMDKV310.

Some Exynos5250 silicon may require 1.05v on the MIF to be stable, so to be
safe we can default to 1.05v instead of 1.00v. This can be set optimally later
in the boot process by the kernel.
The 0x6 value for 1.05v comes from the MAX77686 datasheet.

This patch adds support for the Palm Treo 680 smartphone. A quick overview of
u-boot implementation on the treo 680...
The treo 680 has a Diskonchip G4 nand flash chip. This device has a 2k region
that maps to the system bus at the reset vector in a NOR-like fashion so that it
can be used as the boot device. The phone is shipped with this 2k region
configured as write-protected (can't be modified) and programmed with an initial
program loader (IPL). At power-up, this IPL loads the contents of two flash
blocks to SDRAM and jumps to it. The capacity of the two blocks is not large
enough to hold all of u-boot, so a u-boot SPL is used. To conserve flash space,
these two blocks and the necessary number of subsequent blocks are programmed
with a concatenated spl + u-boot image. That way, the IPL will also load a
portion of u-boot proper, and when the spl runs, it relocates the portion of
u-boot that the IPL has already loaded, and then resumes loading the remaining
part of u-boot before jumping to it.
The default_environment is used (CONFIG_ENV_IS_NOWHERE) because I didn't think
that having a writable environment was worth the cost of a flash block, although
adding it would be straightforward. I abuse the CONFIG_EXTRA_ENV_SETTINGS
option to specify the usbtty for the console (CONFIG_SYS_CONSOLE_IS_IN_ENV).
Support for the LCD is included, but currently it is only useful for displaying
the u-boot splash screen. But if u-boot is built without the usbtty console, it
does display the auto-boot progress nicely.

This patch adds support for the CPLD GPIO bus found on some LaCie boards
(as the 2Big/5Big Network v2 and the 2Big NAS). This parallel GPIO bus
exposes two registers (address and data). Each of this register is made
up of several dedicated GPIOs. An extra GPIO is used to notify the CPLD
that the registers have been updated.
Mostly this bus is used to configure the LEDs on LaCie boards.

Detect if we are running on a panda revision A1-A6,
or an ES panda board. This can be done by reading
the level of GPIOs and checking the processor revisions.
This should result in:
Panda 4430:
GPIO171, GPIO101, GPIO182: 0 1 1 => A1-A5
GPIO171, GPIO101, GPIO182: 1 0 1 => A6
Panda ES:
GPIO2, GPIO3, GPIO171, GPIO48, GPIO182: 0 0 0 1 1 => B1/B2
GPIO2, GPIO3, GPIO171, GPIO48, GPIO182: 0 0 1 1 1 => B3
Set the board name appropriately for the board revision that
is detected.
Update the findfdt macro to load the a4 device tree binary.

smdk5250.c: This file shall contain the code which supports non-FDT.
version. Any addition of non-FDT support for any module
needs to be added in this file.
May be, the file smdk5250.c can be removed in near future
when non-FDT is not required.
The Makefile is updated to compile only one of the files
exynos5-dt.c / smdk5250.c based on FDT configuration.
NOTE:
Please note that all additions corresponding to FDT need to be added into the
file exynos5-dt.c.
At same time if non-FDT support is required then add the corresponding
updations into smdk5250.c.

The number of gpio signal is packed inside CONFIG_SF_DEFAULT_CS macro
(shifted and or'ed with chip select), so it's incorrect to pass
that macro directly as an argument to gpio_direction_output() call.
Also, SPI driver sets the direction and initial value of a gpio,
used as a chip select signal, before any actual activity happens
on the bus.
So, it is safe to just remove the gpio_direction_output call,
that works incorrectly, thus making no effect, anyway.
