U-Boot expects the FDT to be located right after the _end

The "basic" LOAD_FIT path is aware of this limitation, and relocates
the FDT at the expected location. Guessing the expected location
probably only works reliably on 32-bit arm, and it feels like a hack.
One proposal would be to pass the FDT address to u-boot

The correct FDT to use is described by the "fdt" property of the
configuration node. When the fit_unamep argument to fit_image_load()
is "fdt", we get the "/images/fdt" node. This is incorrect, as it
ignores the "fdt" property of the config node, and in most cases,
the "/images/fdt" node doesn't exist.
Use NULL for the 'fit_unamep' argument. With NULL, fit_image_load()
uses the IH_TYPE_FLATDT value to read the config property "fdt",
which points to the correct FDT node(s).
fit_image_load() should probably be split into a function that reads
an image by name, and one that reads an image by config reference. I
don't make those decisions, I just point out the craziness.

spl_load_fit_image() will try to load an image at the address given
in the "load" property. Absent such property, it uses
image_info->load_addr
Correct use of this is demonstrated in spl_fit_append_fdt(), which
resets the 'load_addr' before each spl_load_fit_image() call.
On the other hand loading "loadables" loop in spl_load_simple_fit()
completely ignores this. It re-uses the same structure, but doesn't
reset load_addr. If loadable [i] does not have a "load" property, its
load address defaults to load_addr, which still contains the address
of loadable [i - 1].
A simple solution is to treat NULL as an invalid load address. The
caller can set load_addr = 0 to request an abort if the "load"
property is absent.

When a FIT config specifies a devicetree, we should load it, no
questions asked. In the case of the "simple" FIT loading path, a
difficulty arises in selecting the load address of the FDT.
The default FDT location is right after the "kernel" or "firmware"
image. However, if that is an OP-TEE image, then the FDT may end up in
secure DRAM, and not be accessible to normal world kernels.
Although the best solution is to be more careful about the FDT
address, a viable workaround is to only append the FDT after a u-boot
or Linux image. This is identical to the previous logic, except that
FDT loading is extended to IH_OS_LINUX images.

Fit images were loaded to a buffer provided by spl_get_load_buffer().
This may work when the FIT image is small and fits between the start
of DRAM and SYS_TEXT_BASE.
One problem with this approach is that the location of the buffer may
be manipulated by changing the 'size' field of the FIT. A maliciously
crafted FIT image could place the buffer over executable code and be
able to take control of SPL. This is unacceptable for secure boot of
signed FIT images.
Another problem is with larger FIT images, usually containing one or
more linux kernels. In such cases the buffer be be large enough so as
to start before DRAM (Figure I). Trying to load an image in this case
has undefined behavior.
For example, on stm32mp1, the MMC controller hits a RX overrun error,
and aborts loading.

One possibility that was analyzed was to remove the negative offset,
such that the buffer starts at SYS_TEXT_BASE. This is not a proper
solution because on a number of platforms, the malloc buffer() is
placed at a fixed address, usually after SYS_TEXT_BASE. A large
enough FIT image could cause the malloc()'d data to be overwritten

The solution proposed here is to replace the ad-hoc heuristics of
spl_get_load_buffer() with malloc(). This provides two advantages:
* Bounds checking of the buffer region
* Guarantees the buffer does not conflict with other memory
The first problem is solved by constraining the buffer such that it
will not overlap currently executing code. This eliminates the chance
of a malicious FIT being able to replace the executing SPL code prior
to signature checking.
The second problem is solved in conjunction with increasing
CONFIG_SYS_SPL_MALLOC_SIZE. Since the SPL malloc() region is
carefully crafted on a per-platform basis, the chances of memory
conflicts are virtually eliminated.

Some boards, specifically 64-bit Allwinner boards (sun50i), are
extremely limited on SPL size. One strategy that was used to make space
was to remove the FIT "os" property parsing code, because it uses a
rather large lookup table.
However, this forces the legacy FIT parsing code path, which requires
the "firmware" entry in the FIT to reference the U-Boot binary, even if
U-Boot is not the next binary in the boot sequence (for example, on
sun50i boards, ATF is run first).
This prevents the same FIT image from being used with a SPL with
CONFIG_SPL_FIT_IMAGE_TINY=n and CONFIG_SPL_ATF=y, because the boot
method selection code looks at `spl_image.os`, which is only set from
the "firmware" entry's "os" property.
To be able to use CONFIG_SPL_ATF=y, the "firmware" entry in the FIT
must be ATF, and U-Boot must be a loadable. For this to work, we need to
parse the "os" property just enough to tell U-Boot from other images, so
we can find it in the loadables list to append the FDT, and so we don't

So add the minimal code necessary to distinguish U-Boot/non-U-Boot
loadables with CONFIG_SPL_FIT_IMAGE_TINY=y. This adds about 300 bytes,
much less than the 7400 bytes added by CONFIG_SPL_FIT_IMAGE_TINY=n.

Commit 40686c394e ("riscv: Clean up IPI initialization code")
caused U-Boot failed to boot on SiFive HiFive Unleashed board.
The codes inside arch_cpu_init_dm() may call U-Boot timer APIs
before the call to riscv_init_ipi(). At that time the timer register
base (e.g.: the SiFive CLINT device in this case) is unknown yet.
It might be the name riscv_init_ipi() that misleads people to only
consider it is related to IPI, but in fact the timer capability is
provided by the same SiFive CLINT device that provides the IPI.
Timer capability is needed for both UP and SMP.
Considering that the original refactor does have benefits, that it
makes the IPI code more similar to U-Boot initialization idioms.
It also removes some quite ugly macros. Let's do the minimal revert
instead of a complete revert, plus a fixes to arch_cpu_init_dm() to
consider the SPL case.

The Linux coding style guide (Documentation/process/coding-style.rst)
clearly says:
It's a **mistake** to use typedef for structures and pointers.
Besides, using typedef for structures is annoying when you try to make
headers self-contained.
Let's say you have the following function declaration in a header:
void foo(bd_t *bd);
This is not self-contained since bd_t is not defined.
To tell the compiler what 'bd_t' is, you need to include <asm/u-boot.h>
#include <asm/u-boot.h>
void foo(bd_t *bd);
Then, the include direcective pulls in more bloat needlessly.
If you use 'struct bd_info' instead, it is enough to put a forward
declaration as follows:
struct bd_info;
void foo(struct bd_info *bd);
Right, typedef'ing bd_t is a mistake.
I used coccinelle to generate this commit.
The semantic patch that makes this change is as follows:

This change allows more fine tuning of driver model based SPI support in
SPL and TPL. It is now possible to explicitly enable/disable the DM_SPI
support in SPL and TPL via Kconfig option.
Before this change it was necessary to use:
/* SPI Flash Configs */
#if defined(CONFIG_SPL_BUILD)
#undef CONFIG_DM_SPI
#undef CONFIG_DM_SPI_FLASH
#undef CONFIG_SPI_FLASH_MTD
#endif
in the ./include/configs/<board>.h, which is error prone and shall be
avoided when we strive to switch to Kconfig.
The goal of this patch:
Provide distinction for DM_SPI support in both U-Boot proper and SPL (TPL).
Valid use case is when U-Boot proper wants to use DM_SPI, but SPL must
still support non DM driver.
Another use case is the conversion of non DM/DTS SPI driver to support
DM/DTS. When such driver needs to work in both SPL and U-Boot proper, the
distinction is needed in Kconfig (also if SPL version of the driver
supports OF_PLATDATA).
In the end of the day one would have to support following use cases (in
single driver file - e.g. mxs_spi.c):
- U-Boot proper driver supporting DT/DTS
- U-Boot proper driver without DT/DTS support (deprecated)
- SPL driver without DT/DTS support
- SPL (and TPL) driver with DT/DTS (when the SoC has enough resources to
run full blown DT/DTS)
- SPL driver with DT/DTS and SPL_OF_PLATDATA (when one have constrained
environment with no fitImage and OF_LIBFDT support).
Some boards do require SPI support (with DM) in SPL (TPL) and some only
have DM_SPI{_FLASH} defined to allow compiling SPL.
This patch converts #ifdef CONFIG_DM_SPI* to #if CONFIG_IS_ENABLED(DM_SPI)
and provides corresponding defines in Kconfig.

In a loading chain SPL -> ATF (->OP-TEE) -> U-Boot, ATF and a subsequent

information about usable memory ranges.
Especially OP-TEE needs this to initialize dynamic shared memory
(the only type U-Boot implements when talking to OP-TEE).
So allow spl_fixup_fdt() to take a fdt_blob argument, falling back to
the existing CONFIG_SYS_SPL_ARGS_ADDR if needed and call it from the
ATF path as well.

Currently, they fail to build with CONFIG_SPL_SERIAL=n, because the

preloader_console_init, but make it no-op when CONFIG_SPL_SERIAL=n.
For the few boards that did check for CONFIG_SPL_SERIAL before calling
