The Juno Development Platform is a physical Versatile Express
device with some differences from the emulated semihosting
models. The main difference is that the system is split in
a SoC and an FPGA where the SoC hosts the serial ports at
totally different adresses.

The Versatile Express ARMv8 semihosted FVP platform is still
using the legacy CONFIG_SYS_EXTRA_OPTIONS method to configure
some compile-time flags. Get rid of this and create a Kconfig
entry for the FVP model, and a selectable bool for the
semihosting library.
The FVP subboard is now modeled as a target choice so we can
eventually choose between different ARMv8 versatile express
boards (FVP, base model, Juno...) this way. All dependent
symbols are updated to reflect this.
The 64bit Versatile Express board symbols are renamed
VEXPRESS64 so we have some chance to see what is actually
going on. Tested on the FVP fast model.

Added the lowlevel_init to enable the Neon instructions.
Initially the u-boot was causing undefined instruction
exception if loaded through tcl, and working fine if loaded
through FSBL. The exception was causing in convertion formula

were disabled and hence causing the undefined exception. In

If CONFIG_OF_CONTROL is enabled, lib/fdtdec.c is compiled.
It includes <asm/gpio.h> and then <asm/gpio.h> includes
<asm/arch/gpio.h>. As a result, all the SoCs that enable
CONFIG_OF_CONTROL must have <asm/arch/gpio.h> even if they
do not support GPIO.
The right fix would be to split the lib/fdtdec.c to remove
dependency on GPIO.This commit adds a dummy <asm/arch/gpio.h>
to support OF_CONTROL for LS102x platform. This dummy header
will be removed after FDT-GPIO stuff is fixed correctly.

The DDR PHY training function, ddrphy_prepare_training() would not
work if compiled with GCC 4.9.
The struct ddrphy (arch/arm/include/asm/arch-uniphier/ddrphy-regs.h)
is specified with __packed because it represents a hardware register
mapping, but it turned out to cause a problem on GCC 4.9.
If -mno-unaligned-access is specified (yes, it is in
arch/arm/cpu/armv7/config.mk), GCC 4.9 is aware of the
__attribute__((packed)) and generates extra instructions to perform
the memory access in a way that does not cause unaligned access.
(Actually it is not need here because the register base, the first
argument of the ddrphy_prepare_training(), is always given with a
4-byte aligned address.)
Anyway, as a result, readl() / writel() is divided into byte-wise
accesses. The problem is that this hardware only accepts 4-byte
register access. Byte-wise accesses lead to unexpected behavior.
There are some options to avoid this problem.
[1] Remove -mno-unaligned-access
[2] Add __aligned(4) along with __packed to struct ddrphy
[3] Remove __packed from struct ddrphy
[1] solves the problem for ARMv7, but it does not for pre-ARMv6 and
ARMv6-M architectures where -mno-unaligned-access is default.
So, [1] does not seem reasonable in terms of code portability.
Both [2] and [3] work well, but [2] seems too much. All the members
of struct ddrphy have the u32 type. No padding would be inserted
even if __packed is dropped.
