The initial environment is linked to the u-boot binary. Modifying the
environment from User Space with the env tools requires that the tools
are always built together with the bootloader to be sure that they
contain the initial environment in case no environment is stored into
persistent storage or when a board boots with just the default
environment. This makes difficult for distros to provide a general
package to access the environment. A simpler way is if the tools are
generic for all boards and a configuration file is given to provide the
initial environment.
The patch just generates the initial environment by extracting it from
the compiled object. This file can then be used for tools in user space
to initialize the environment.

mkimage-imx8 and the various boot binaries are taken from.

Porting the cadence USB3 (CDNS3) driver from kernel to u-boot. We only support
the gadget (device mode), while the host mode is not supported. Users remains
to use xhci-imx8 driver for host mode.
Some changes in the CDNS3 driver porting:
1. Add match_ep call back to usb_gadget_ops. The CDNS3 gadget driver replies
on this operation to bind the usb_ep/usb_ss_ep with the endpoint descriptor
when function layer uses usb_ep_autoconfig to add endpoint descriptors to gadget.
So that CDNS3 driver can know the EP information and configure the EP once the
set configuration request is received.
2. U-boot does not have CMA, so it won't allocate uncached memory. Need to flush
TRB and its DMA buffer before prime to usb controller and after complete transfer.
3. In core.c, we add functions to hook with u-boot. It needs uplayer like
to pass the register base address of each part of the USB controller.
4. Force the CDNS3 gadget max speed to HS. The SuperSpeed is not supported by u-boot,
so disable it in gadget driver. A configuration USB_CDNS3_GADGET_FORCE_HIGHSPEED is
selected.
5. Added gadget_is_cdns3 checking to provide bcdUSB value in device descriptor.
6. Moved some new fields in usb_ep structure to usb_ss_ep, since u-boot does not have them.
7. Remove host part codes as it is not supported by this driver.

Most of architectures have .text section situated in the very beginning
of U-Boot binary and thus it is very logical that CONFIG_SYS_TEXT_BASE
is used on final linkage step to specify where U-Boot gets linked to.
For that we pass the following construction to the LD:
---------------------------->8-----------------------
xxx-ld ... -Ttext $(CONFIG_SYS_TEXT_BASE) ...
---------------------------->8-----------------------
But there could be exceptions. For example:
1. In case of ARCv2 we want to put vectors table in its own section
.ivt in front of .text section which means we need either add an
offset to CONFIG_SYS_TEXT_BASE to compensate for .ivt or don't
pass "-Ttext" to the LD at all and specify link base in linker
script directly.
2. Some architectures even though have .text section in the very
beginning of the U-Boot image still use different symbols to
specify link-base:
* NIOS2: CONFIG_SYS_MONITOR_BASE (which I really like because
that exactly what makes sense - where out image starts but not
beginning of its .text section which just happened to match the
whole image beginning)
* EXTENSA: CONFIG_SYS_TEXT_ADDR
* X86: Which doesn't use CONFIG_SYS_MONITOR_BASE in case of EFI
otherwise sets explicit link base in u-boot.lds
I think that's good to allow for flexibility and don't require each and
every architecture or even platform to specify CONFIG_SYS_TEXT_BASE as well
as use it to set .text section location.
So let's only pass "-Ttext xxx" for those architectures who don't set
link-base explicitly in their linker scripts.

With CONFIG_SYS_INIT_SP_BSS_OFFSET enabled, the initial (pre-relocation)
stack is placed some distance after bss_start. The control DTB is appended
to the U-Boot binary at bss_start. If the DTB is too large, or the SP BSS
offset too small, then the initial stack could corrupt the DTB. Enhance
the Makefile to check whether this is likely to occur.

Update tegra to use binman for image creation. This still includes the
current Makefile logic, but a later patch will remove this. Three output
files are created, all of which combine
SPL and U-Boot:
u-boot-tegra.bin - standard image
u-boot-dtb-tegra.bin - same as u-boot-tegra.bin
u-boot-nodtb-target.bin - includes U-Boot without the appended device tree
The latter is useful for build systems where the device is appended later,
perhaps after being modified.

When building on a multi-core machine for an SPL-enabled board that
also uses CONFIG_OF_EMBED, the following error can be encountered
due to a race condition:
make[3]: *** No rule to make target 'spl/dts/dt.dtb.o', needed by
'spl/dts/built-in.o'. Stop.
../scripts/Makefile.spl:364: recipe for target 'spl/dts' failed
make[2]: *** [spl/dts] Error 2
make[2]: *** Waiting for unfinished jobs....
A reliable way to trigger this race condition is to add "sleep 60" to
the end of the "arch-dtbs" rule's recipe in "dts/Makefile" and to build
U-Boot against a board which uses the CONFIG_OF_EMBED and CONFIG_SPL
options using "make -j8" or a similar command.
This commit corrects this race condition via the use of CONFIG_OF_EMBED
in the same way that commit 3c00a2c8b5e2 ("Makefile: Correct dependency
race condition with TPL") and commit 054b3a1e80fc ("dm: Makefile: Build
of-platdata before SPL") use CONFIG_OF_SEPARATE.

Currently, pylibfdt is always compiled if swig is installed on your
machine. It is really annoying because most of targets (excepts
x86, sunxi, rockchip) do not use dtoc or binman.
"checkbinman" and "checkdtoc" are wrong. It is odd that the final
build stage checks if we have built necessary tools. If your platform
depends on dtoc/binman, you must be able to build pylibfdt. If swig
is not installed, it should fail immediately.
I added PYLIBFDT, DTOC, BINMAN entries to Kconfig. They should be
property select:ed by platforms that need them. Kbuild will descend
into scripts/dtc/pylibfdt/ only when CONFIG_PYLIBFDT is enabled.

The pylibfdt is used by dtoc (and, indirectly by binman), but there
is no reason why it must be generated in the tools/ directory.
Recently, U-Boot switched over to the bundled DTC, and the directory
structure under scripts/dtc/ now mirrors the upstream DTC project.
So, scripts/dtc/pylibfdt is the best location.
I also rewrote the Makefile in a cleaner Kbuild style.
The scripts from the upstream have been moved as follows:
lib/libfdt/pylibfdt/setup.py -> scripts/dtc/pylibfdt/setup.py
lib/libfdt/pylibfdt/libfdt.i -> scripts/dtc/pylibfdt/libfdt.i_shipped
The .i_shipped is coped to .i during building because the .i must be
located in the objtree when we build it out of tree.

Up to now we depended on an exported variable to build u-boot.rom.
We should be able to specify it in the configuration file, too.
With this patch this becomes possible using the new Kconfig option
CONFIG_BUILD_ROM.

qemu-x86_defconfig and qemu-x86_64_defconfig.

On some systems `python` is `python3` (for instance, Archlinux). The
`PYTHON` variable can be used to point to `python2` to have a successful
build.
The use of `PYTHON` is currently limited in the Makefile and needs to be
extended in other places:
First, pylibfdt is required to be a Python 2 binding (binman imports
pylibfdt and is only compatible Python 2), so its setup.py needs to be
called accordingly. An alternative would be to change the libfdt
setup.py shebang to python2, but the binding is actually portable. Also,
it would break on system where there is no such thing as `python2`.
Secondly, the libfdt import checks need to be done against Python 2 as
well since the Python 2 compiled modules (in this case _libdft.so) can
not be imported from Python 3.
Note on the libfdt imports: "@if ! PYTHONPATH=tools $(PYTHON) -c 'import
libfdt'; then..." is probably simpler than the currently sub-optimal
pipe.

For the RK3368, we want to use OF_PLATDATA in TPL, but full OF_CONTROL
in SPL: this requires the introduction of a new family of
configuration options to decouple SPL_OF_CONTROL and SPL_OF_PLATDATA

Consequently, Makefile.spl needs to be adjusted to test for these

hard-coding the SPL variant.
