At present panic() is in the vsprintf.h header file. That does not seem
like an obvious choice for hang(), even though it relates to panic(). So
let's put hang() in its own header.

commit 4aba5fb857 ("arm: zynq: Rework FPGA initialization")
moved FPGA initialization from board_init() to arch_early_init_r(),
which is not called as part of the SPL
Fix this by calling arch_early_init_r() in the spl_board_init()
function, so the FPGA is correctly initialized

But there is no reason not to enabled it based on macros.

When U-Boot started using SPDX tags we were among the early adopters and
there weren't a lot of other examples to borrow from. So we picked the
area of the file that usually had a full license text and replaced it
with an appropriate SPDX-License-Identifier: entry. Since then, the
Linux Kernel has adopted SPDX tags and they place it as the very first
line in a file (except where shebangs are used, then it's second line)
and with slightly different comment styles than us.
In part due to community overlap, in part due to better tag visibility
and in part for other minor reasons, switch over to that style.
This commit changes all instances where we have a single declared
license in the tag as both the before and after are identical in tag
contents. There's also a few places where I found we did not have a tag
and have introduced one.

We have a large number of places where while we historically referenced
gd in the code we no longer do, as well as cases where the code added
that line "just in case" during development and never dropped it.

The goal of this patch is to clean up the code related to choosing SPL
MMC boot mode.
The spl_boot_mode() now is called only in spl_mmc_load_image() function,
which is only compiled in if CONFIG_SPL_MMC_SUPPORT is enabled.
To achieve the goal, all per mach/arch implementations eligible for
unification has been replaced with one __weak implementation.

The SPL code already knows which boot device it calls the spl_boot_mode()
on, so pass that information into the function. This allows the code of
spl_boot_mode() avoid invoking spl_boot_device() again, but it also lets
board_boot_order() correctly alter the behavior of the boot process.
The later one is important, since in certain cases, it is desired that
spl_boot_device() return value be overriden using board_boot_order().

We should not init the console this early since it precludes using driver
model for the UART, since it is not set up at the start of board_init_f().
See the README for more information. The debug UART does not have this
restriction. If we want to do early init with the console on it can be done
in spl_board_init().
Move the preloader_console_init() call from board_init_f() to board_init_r().

Due to licensing issues, the files ps7_init.c/h are not able to be
distributed with U-Boot source code. Recent Xilinx tools also
provide the GPL variants (ps7_init_gpl.c/h), compatible with U-Boot
license.
Prior to this commit, we had to copy ps7_init files into
board/xilinx/zynq/ before the compile.
To be more user-friendly, let's include ps7_init_gpl.c/h for
Zedboard, MicroZed, ZC702, ZC706.
These init code have been taken from the hwplatform_templates
directory of Xilinx SDK 2014.4.
You can still use customized ps7_init_gpl.c/h by enabling
CONFIG_ZYNQ_CUSTOM_INIT. The recommended directory for storing them
is now board/xilinx/zynq/custom_hw_platform, but board/xilinx/zynq
is still supported for backward compatibility. The latter emits
a warning message to prompt users to gradually switch to the new
directory.
