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.

The dram_init and dram_init_banksize functions were using a board
specific implementation for decoding the memory banks from the fdt. This
board specific implementation uses a static variable 'tmp' which makes
these functions unsafe for execution from within the board_init_f
context.
This unsafe use of a static variable was causing a specific bug when
using the zynq_zybo configuration, U-Boot would generate the following
error during image load. This was caused due to dram_init overwriting
the relocations for the 'image' variable within the do_bootm function.
Out of coincidence the un-initialized memory has a compression type
which is the same as the value for the relocation type R_ARM_RELATIVE.
Uncompressing Invalid Image ... Unimplemented compression type 23
It should be noted that this is just one way the issue could surface,
other cases my not be observed in normal boot flow. Depending on the
size of various sections, and location of relocations within __rel_dyn
and the compiler/linker the outcome of this bug can differ greatly.
This change makes the dram_init* functions use a generic implementation
of decoding and populating memory bank and size data.

The dram_init* functions for the zynq board are not safe for use from
the board_init_f stage due to its use of the 'tmp' static variable.
This incorrect use of a static variable was causing rare issues where
the dram_init function would overwrite some parts the __rel_dyn section
which caused obscure failures.
Using the zynq_zybo configuration, U-Boot would generate the following
error during image load. This was caused due to dram_init overwriting

This change removes the existing code and copies the implementation of
the dram_init and dram_init_banksize from the
arch/arm/mach-uniphier/dram_init.c source. This version of these
functions does not use static variables and behaves the same (reading
banks from fdt, and using the first bank as the ram_size).

We have flipped CONFIG_SPL_DISABLE_OF_CONTROL. We have cleansing
devices, $(SPL_) and CONFIG_IS_ENABLED(), so we are ready to clear
away the ugly logic in include/fdtdec.h:
#ifdef CONFIG_OF_CONTROL
# if defined(CONFIG_SPL_BUILD) && !defined(SPL_OF_CONTROL)
# define OF_CONTROL 0
# else
# define OF_CONTROL 1
# endif
#else
# define OF_CONTROL 0
#endif
Now CONFIG_IS_ENABLED(OF_CONTROL) is the substitute. It refers to
CONFIG_OF_CONTROL for U-boot proper and CONFIG_SPL_OF_CONTROL for
SPL.
Also, we no longer have to cancel CONFIG_OF_CONTROL in
include/config_uncmd_spl.h and scripts/Makefile.spl.

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.

This commit introduces separate configuration for them, which makes

Going forward, the recommended build commands are:
