0dac6b4e85 net: Move the VCI and client arch values to Kconfig
We have a bunch of boards that define their vendor class identifier and
client archs in the board files or in the distro config. Move everything
to the generic Kconfig options.

We're missing the distinction between i386 and x86_64, as I couldn't find
any config variable that would tell us the difference. Is that really important
to people? I guess not, so I left it out.

7babe48252 arm64: Juno/FVP: adjust kernel load address
The default kernel load offset for an arm64 kernel is 0x80000, so
U-Boot takes cares of moving the loaded kernel to a matching memory
location just before booting it.
Since we run with caches off, this takes a while for any decently
sized kernel - with no output explaining the reason for the delay
(unless one uses a DEBUG build).
By adjusting the default load offset for Juno and VFP to be 512K
aligned in the first place we can skip this copying and boot much
faster.
Tested on Juno.

f3c71c93d7 vexpress64: store env in flash
Add support for storing the environment in CFI NOR flash on Juno and FVP
models.

I also removed some config values that are not used by CFI flash parts.

Juno has 1 flash part with 259 sectors.  The first 255 sectors are
0x40000 (256kb) and are followed by 4 sectors of 0x10000 (64KB).

FVP models simulate a 64MB NOR flash part at base address 0x0FFC0000.
This part has 256 x 256kb sectors.  We use the last sector to store the
environment.

To save the NOR flash to a file, the following parameters should be
passed to the model:

    -C bp.flashloader1.fname=${FILENAME}
    -C bp.flashloader1.fnameWrite=${FILENAME}

Foundation models don't simulate the NOR flash, but having NOR support
in the u-boot binary does not harm:  attempting to write to the NOR will
fail gracefully.

ecbed5d6f4 vexpress64: juno: add alternate kernel and device tree filenames
The latest Juno firmware stores the files in NOR flash as "norkern" for
kernel binary, "board.dtb" for the device tree binary.

The "old" firmware used the name "Image" for the kernel binary and
"juno" for the device tree binary.

Rather than just change the default U-Boot configuration to use the new
names, breaking users with the old firmware, attempt to load the default
filename first.  If that fails, attempt to load the alternate filename.

I've echo'd that we are loading the alternate file to counter the
output from "afs load" shown if the first load attempt fails.  For
example, I see output like this on my Juno board when it's configured
the with the "old" firmware:

    image "norkern" not found in flash
    Loading Image instead of norkern
    loaded region 0 from 08500000 to 80000000, 00AB6318 bytes
    image "board.dtb" not found in flash
    Loading juno instead of board.dtb
    loaded region 0 from 0A000000 to 83000000, 00003188 bytes

181bd9dc61 kconfig: add config option for shell prompt
Add option to set shell prompt string from menuconfig and migrate
boards globally.

The migration is done as follows:
- Boards that explicitly and unconditionally set CONFIG_SYS_PROMPT had the
  entry moved to their defconfig files.
- Boards that defined some kind of #ifdef logic which selects the
  CONFIG_SYS_PROMPT (for example qemu-mips) got an #undef CONFIG_SYS_PROMPT
  right before the #ifdef logic and were left alone.
- This change forces CONFIG_SYS_PROMPT to be a per board decision, and thus
  CONFIG_SYS_PROMPT was removed from all <soc>_common.h and <arch>_common.h
  files. This results in a streamlined default value across platforms, and
  includes the following files: spear-common, sunxi-common, mv-common,
  ti_armv7_common, tegra-common, at91-sama5_common, and zynq-common.
- Boards that relied on <arch/soc>_common.h values of CONFIG_SYS_PROMPT were
  not updated in their respective defconfig files under the assumption that
  since they did not explicitly define a value, they're fine with whatever
  the default is.
- On the other hand, boards that relied on a value defined in some
  <boards>_common.h file such as woodburn_common, rpi-common,
  bur_am335x_common, ls2085a_common, siemens_am33x_common, and
  omap3_evm_common, had their values moved to the respective defconfig files.
- The define V_PROMPT was removed, since it is not used anywhere except for
  assigning a value for CONFIG_SYS_PROMPT.

This solution to reserving memory for secure world is not
optimal, so we need to think of how the secure world and
earlier boot stages should communicate to U-Boot what
memory they are eating up. For now let's just put 16MB
aside.

Also enable the memory test command and define start and

is= cmd 51(Q) addr 0000000008000040 is= 00800051 00510051

Debugging showed that the problem could be solved by preventing u-boot
from scanning different flash widths by specifying
CONFIG_SYS_FLASH_CFI_WIDTH so that only using the 'correct' width was
used.

d280ea00ef vexpress64: use DM for all vexpress64 boards
Commit d8bafe1310
"ARMv8: enable DM in vexpress64 board" only enabled DM
for the simulated vexpress64 board (FVP) with the
hardcoded clock value for the simulated board, causing
a console regression on the Juno board which was using
a different clock setting.

Fix this by enabling DM for all vexpress64 boards,
defining the clock frequency per-board, deleting the
static array of PL01x ports from the config file and
relying solely on the port defined in the boardfile
using platform data.

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.

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.

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

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.
