49995ffe81 vexpress64: remove board late init, use smhload
This removes the kludgy late board init from the FVP simulator
version of Versatile Express 64bit (ARMv8), and replace it with
a default boot command using the new smhload command to load
the files using semihosting. Tested on the Foundation Model.

23b5877c64 armv8/vexpress64: make multientry conditional
While the Freescale ARMv8 board LS2085A will enter U-Boot both
on a master and a secondary (slave) CPU, this is not the common
behaviour on ARMv8 platforms. The norm is that U-Boot is entered
from the master CPU only, while the other CPUs are kept in
WFI (wait for interrupt) state.

The code determining which CPU we are running on is using the
MPIDR register, but the definition of that register varies with
platform to some extent, and handling multi-cluster platforms
(such as the Juno) will become cumbersome. It is better to only
enable the multiple entry code on machines that actually need
it and disable it by default.

Make the single entry default and add a special
ARMV8_MULTIENTRY KConfig option to be used by the
platforms that need multientry and set it for the LS2085A.
Delete all use of the CPU_RELEASE_ADDR from the Vexpress64
boards as it is just totally unused and misleading, and
make it conditional in the generic start.S code.

This makes the Juno platform start U-Boot properly.

This enables the vexpress64 to detect its NOR flash so that we
can load kernel etc from it.

b31f9d7a4a vexpress64: juno: support SMC9118 ethernet
This configures the Juno board to enable ethernet using the
SMSC9118 ethernet controller found in the board. Tested by
TFTP-booting a kernel over ethernet.

ffc103732c vexpress64: support the Juno Development Platform
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.

f91afc4d00 vexpress64: get rid of CONFIG_SYS_EXTRA_OPTIONS
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.

03ca6a394a vexpress64: switch to generic board
The few Versatile Express ARMv8 platforms we have may just as
well be switched to generic board from the beginning.

Tested on the ARM foundation model and the in progress support
for the ARMv8 Juno board.

261d27605c arm: Add support for semihosting for armv8 fastmodel targets.
The armv8 ARM Trusted Firmware (ATF) can be used to load various ATF
images and u-boot, and does this for virtual platforms by using
semihosting. This commit extends this idea by allowing u-boot to also
use semihosting to load the kernel/ramdisk/dtb. This eliminates the need
for a bootwrapper and produces a more realistic boot sequence with
virtual models.

Though the semihosting code is quite generic, support for armv7 in
fastmodel is less useful due to the wide range of available silicon
and the lack of a free armv7 fastmodel, so this change contains an
untested armv7 placeholder for the service trap opcode.

Please refer to doc/README.semihosting for a more detailed description
of semihosting and how it is used with the armv8 virtual platforms.

c71645ad2b arm64 patch: gicv3 support
This patch add gicv3 support to uboot armv8 platform.

Changes for v2:
  - rename arm/cpu/armv8/gic.S with arm/lib/gic_64.S
  - move smp_kick_all_cpus() from gic.S to start.S, it would be
    implementation dependent.
  - Each core initialize it's own ReDistributor instead of master
    initializeing all ReDistributors. This is advised by arnab.basu
    <arnab.basu@freescale.com>.

3865ceb726 vexpress/armv8: Fix incorrect ethernet controller
This patch enables ethernet support in ARMv8 foundation model. The ARMv8
foundation model supports a SMSC91C111 integrated MAC and PHY module
which is present at base address 0x01A000000.

The previous implementation had enabled SMSC9115 ethernet controller
which is not present on the ARMv8 foundation model.

Tested on ARMv8 foundation model v1 and v2 by running ping/tftp
between the foundation model and the host PC via a bridged network.
