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
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.
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.

Prior to this commit, ZC702 and ZC706 shared the same configuration
and were built as follows:
ZC702: make zynq_zc70x_defconfig && make
ZC706: make zynq_zc70x_defconfig && make DEVICE_TREE=zynq-zc706
This commit introduces separate configuration for them, which makes
the next commit much easier.
Going forward, the recommended build commands are:
ZC702: make zynq_zc702_defconfig && make
ZC706: make zynq_zc706_defconfig && make
Although the old work flow is still supported, CONFIG_TARGET_ZC70X
has been marked as deprecated. If used, the warning message is
shown to prompt users to switch to the new scheme.

Going forward, please use ps7_init_gpl.c/h all the time.
If you are still using old Xilinx tools that are only able to

We have switched to Kconfig and the boards.cfg file is going to
be removed. We have to retrieve the board status and maintainers
information from it.
The MAINTAINERS format as in Linux Kernel would be nice
because we can crib the scripts/get_maintainer.pl script.
After some discussion, we chose to put a MAINTAINERS file under each
board directory, not the top-level one because we want to collect
relevant information for a board into a single place.
TODO:

This commit adds:
- arch/${ARCH}/Kconfig
provide a menu to select target boards
- board/${VENDOR}/${BOARD}/Kconfig or board/${BOARD}/Kconfig
set CONFIG macros to the appropriate values for each board
- configs/${TARGET_BOARD}_defconfig
default setting of each board
(This commit was automatically generated by a conversion script
based on boards.cfg)
In Linux Kernel, defconfig files are located under
arch/${ARCH}/configs/ directory.
It works in Linux Kernel since ARCH is always given from the
command line for cross compile.
But in U-Boot, ARCH is not given from the command line.
Which means we cannot know ARCH until the board configuration is done.
That is why all the "*_defconfig" files should be gathered into a
single directory ./configs/.

The files ps7_init.c and ps7_init.h are supposed to be generated by

rather than

ps7_init.c and ps7_init.h are supposed to be exported by hw project
and copied to board/xilinx/zynq/ directory.
We want them to be ignored by git.
So what we should do is to always treat them as external files
rather than replacing ps7_init.c
This commit does:
- Move a weak function ps7_init() to arch/arm/cpu/armv7/zynq/spl.c
and delete board/xilinx/zynq/ps7_init.c
- Compile board/xilinx/zynq/ps7_init.c only when it exists
- Add .gitignore to ignore ps7_init.c/h

ps7_init.c exported by hw project has #include "xil_io.h" line
but U-Boot does not have "xil_io.h".
So we get an error on SPL build:
ps7_init.c:12581:20: fatal error: xil_io.h: No such file or directory
We can delete the include directive in ps7_init.c to avoid this error.
But it is painful to do this every time we export ps7_init.c file.
Instead, we can put an empty xil_io.h in the same directory
so we can directly copy ps7_init.c as is.

When CONFIG_FPGA is defined but CONFIG_SPL_FPGA is not, the build fails:
board.c: In function 'board_init':
board.c:41:3: error: 'fpga' undeclared (first use in this function)
fpga = fpga010;
Fix this by expanding the "#if.." around this block to match the other
FPGA checks and don't compile this block when buildign for SPL without
FPGA support.
Tested a bootloader that had CONFIG_FPGA defined without CONFIG_SPL_FPGA,
this now compiles without errors and loading FPGA from u-boot works.
