Add build target for generating boot partition images recognised by
the SoCFPGA BootROM. The SoCFPGA BootROM expects four copies of the
u-boot-spl-dtb.sfp at the beginning of boot partition. Those are
u-boot-spl-dtb.bin augmented by a header with which the BootROM can
work. The u-boot-dtb.img uImage is appended to this to produce a
full boot partition image, the u-boot-with-spl-dtb.sfp . This is
the name of the final target.

It is useful to be able to load U-Boot onto a board even if is it already
running EFI. This can allow access to the U-Boot command interface, flexible
booting options and easier development.
The easiest way to do this is to build U-Boot as a binary blob and have an
EFI stub copy it into RAM. Add support for this feature, targeting 32-bit
initially.
Also add a way to detect when U-Boot has been loaded via a stub. This goes
in common.h since it needs to be widely available so that we avoid redoing
initialisation that should be skipped.

Secure Boot Target is added for NAND for P3041.
For mpc85xx SoCs, the core begins execution from address 0xFFFFFFFC.
In case of secure boot, this default address maps to Boot ROM.
The Boot ROM code requires that the bootloader(U-boot) must lie
in 0 to 3.5G address space i.e. 0x0 - 0xDFFFFFFF.
In case of NAND Secure Boot, CONFIG_SYS_RAMBOOT is enabled and CPC is
configured as SRAM. U-Boot binary will be located on SRAM configured
at address 0xBFF00000.
In the U-Boot code, TLB entries are created to map the virtual address
0xFFF00000 to physical address 0xBFF00000 of CPC configured as SRAM.

In order to achieve reproducible builds in U-Boot, timestamps that are defined
at build-time have to be somewhat eliminated. The SOURCE_DATE_EPOCH environment
variable allows setting a fixed value for those timestamps.
Simply by setting SOURCE_DATE_EPOCH to a fixed value, a number of targets can be
built reproducibly. This is the case for e.g. sunxi devices.
However, some other devices might need some more tweaks, especially regarding
the image generation tools.

Commit a93648d197 introduced linker generated

linker scripts. Therefore this commit broke these host-tools for them, namely
FreeBSD and Darwin (OS/X).
This commit tries to fix this. In order to have a clean distinction between host
and embedded code space we need to introduce our own linker generated list
instead of re-using the available linker_lists.h provided functionality. So we
copy the implementation used in linux kernel script/mod/file2alias.c which has
the very same problem (cause it is a host tool). This code also comes with an

Instead of defining __UBOOT__ in each source file,
passing it from the top Makefile would be easier.

Copy the Kconfig option from "init/Kconfig" of Linux v3.16 tag
and adjust the help document.

Commit 51148790 added scripts/multiconfig.py written in Python 2
to adjust Kconfig for U-Boot.
It has been hard for Python 3 users because Python 2 and Python 3
are not compatible with each other.
We are not happy about adding a new host tool dependency
(in this case, Python version dependency) for the core build process.
After some discussion, we decided to use only basic tools.
The script may get a bit more unreadable by shell scripting,
but we believe it is worthwhile.
In addition, this commit revives "<board>_config" target that is
equivalent to "<board>_defconfig" for backwards compatibility.
It is annoying to adjust various projects which use U-Boot.

The command generating the "common/system_map.o" file was always shown
during the build making the output messy. Now it is called using the
Kbuild "cmd" macro, so that the full command is shown only when
building in verbose mode.

"make %_config all" was supported for the first time in U-Boot:
commit 53bca5ab
kbuild: support simultaneous board configuration and "make all"
Surprisingly it had not been working in Linux Kernel for a long time.
So I sent back the patch to the Linux Kbuild community and it was
accepted with a little code improvement, at commit 9319f453.
Now, you can do "make defconfig all" or "make %_defconfig all"
in Linux too.
This commit updates some scripts to fill the code-diff
between Linux and U-Boot.

This commit was imported from Linux Kernel:
commit a86fe353 written by me.
W=... provides extra gcc checks.
Having such code in scripts/Makefile.build results in the same flags
being added to KBUILD_CFLAGS multiple times becuase
scripts/Makefile.build is invoked every time Kbuild descends into
the subdirectories.
Since the top Makefile is already too cluttered, this commit moves
all of extra gcc check stuff to a new file scripts/Makefile.extrawarn,
which is included from the top Makefile.

file_size was being calculated using back-ticks but map_size uses
$(shell ...). Update the file_size calculation to use $(shell ...).
From: Jeroen Hofstee <jeroen@myspectrum.nl>
The binary_size_check target relies on stat -c %s
to return the size of u-boot.bin. This only works
with GNU stat though. Use wc instead.

This commit enables Kconfig.
Going forward, we use Kconfig for the board configuration.
mkconfig will never be used. Nor will include/config.mk be generated.
Kconfig must be adjusted for U-Boot because our situation is
a little more complicated than Linux Kernel.
We have to generate multiple boot images (Normal, SPL, TPL)
from one source tree.
Each image needs its own configuration input.
Usage:
Run "make <board>_defconfig" to do the board configuration.
It will create the .config file and additionally spl/.config, tpl/.config
if SPL, TPL is enabled, respectively.
You can use "make config", "make menuconfig" etc. to create
a new .config or modify the existing one.
Use "make spl/config", "make spl/menuconfig" etc. for spl/.config
and do likewise for tpl/.config file.
The generic syntax of configuration targets for SPL, TPL is:
<target_image>/<config_command>
Here, <target_image> is either 'spl' or 'tpl'
<config_command> is 'config', 'menuconfig', 'xconfig', etc.
When the configuration is done, run "make".
(Or "make <board>_defconfig all" will do the configuration and build
in one time.)
For futher information of how Kconfig works in U-Boot,
please read the comment block of scripts/multiconfig.py.
By the way, there is another item worth remarking here:
coexistence of Kconfig and board herder files.
Prior to Kconfig, we used C headers to define a set of configs.
We expect a very long term to migrate from C headers to Kconfig.
Two different infractructure must coexist in the interim.
In our former configuration scheme, include/autoconf.mk was generated
for use in makefiles.
It is still generated under include/, spl/include/, tpl/include/ directory
for the Normal, SPL, TPL image, respectively.

Commit efcf861 (kbuild: use scripts/Makefile.clean)
refactored the cleaning targets and accidentially replaced the actually
generated "ctags" and "etags" files in the file list by "tags" and "TAGS".
"tags" and "TAGS" are not part of the Makefile build targets and
therefore should not be a part of the list for clean targets.
Substitute the actually generated files instead, to fix the clean
targets behavior.

Commit 9e41403 (kbuild: change out-of-tree build)
changed the U-Boot build working directory to the output tree
for the out-of-tree builds.
This broke the {c,e}tags/cscope build targets as TAG_SUBDIRS variable
collected directories based on assumption that the build working
directory is the U-Boot source tree directory.
Fix the {c,e}tags/cscope build targets by adding the $(srctree) prefix.
Also, remove the $(obj) prefix from the etags build target to finish
the $(obj) prefix removal started by the same commit.
