be2d1a87c7 spl: fit: Also record architecture in /fit-images
On ARM64 secure OS can run as 64bit or 32bit that's why it is necessary to
record information about architecture that other code can read it and
properly pass it to TF-A and start in 64bit or 32bit mode.

f0a6ec3656 spl: fit: Don't overwrite previous loadable if "load" is missing
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.

891d9e84a7 spl: Convert spl_fit to work with sandbox
At present this casts addresses to pointers so cannot work with sandbox.
Update the code to use map_sysmem() instead.

As part of this change, the existing load_ptr is renamed to src_ptr since
it is not a pointer to load_addr. It is confusing to use a similar name
for something that is not actually related. For the alignment code,
ALIGN() is used instead of open-coded alignment. Add a comment to the line
that casts away a const.

Use a (new) load_ptr variable to access memory at address load_addr.

71551055cb spl: fit: Load devicetree when a Linux payload is found
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.

e4928270a4 spl: fit: Remove useless loop in spl_fit_get_image_name()
When a desired configuration is not found, conf_node will have a
negative value. Thus the for loop will start at the root "/" node of
the image, print the "/description" property, and stop.

It appears the intent of the loop was to print the names of the
subnodes under "/configurations". We would need the offset to the
"/configurations" node, which is abstracted by fit_find_config_node().

This change agrees that abstracting the node offset is the correct
design, and we shouldn't be parsing the configurations manually. Thus
the loop in spl_fit_get_image_name() is useless. Remove it.

03f1f78a9b spl: fit: Prefer a malloc()'d buffer for loading 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.

        Figure I                                       Figure II

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
(Figure II) when loading.

                 Figure III

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.

3a8ee3df83 board: Rename uclass to sysinfo
This uclass is intended to provide a way to obtain information about a
U-Boot board. But the concept of a U-Boot 'board' is the whole system,
not just one circuit board, meaning that 'board' is something of a
misnomer for this uclass.

In addition, the name 'board' is a bit overused in U-Boot and we want to
use the same uclass to provide SMBIOS information.

The obvious name is 'system' but that is so vague as to be meaningless.
Use 'sysinfo' instead, since this uclass is aimed at providing information
on the system.

Rename everything accordingly.

Note: Due to the patch delta caused by the symbol renames, this patch
shows some renamed files as being deleted in one place and created in
another.

caa7fc2c57 spl: Use standard FIT entries
SPL is creating fit-images DT node when loadables are recorded in selected
configuration. Entries which are created are using entry-point and
load-addr property names. But there shouldn't be a need to use non standard
properties because entry/load are standard FIT properties. But using
standard FIT properties enables option to use generic FIT functions to
descrease SPL size. Here is result for ZynqMP virt configuration:
xilinx_zynqmp_virt: spl/u-boot-spl:all -82 spl/u-boot-spl:rodata -22 spl/u-boot-spl:text -60

The patch causes change in run time fit image record.
Before:
fit-images {
        uboot {
                os = "u-boot";
                type = "firmware";
                size = <0xfd520>;
                entry-point = <0x8000000>;
                load-addr = <0x8000000>;
        };
};

After:
fit-images {
        uboot {
                os = "u-boot";
                type = "firmware";
                size = <0xfd520>;
                entry = <0x8000000>;
                load = <0x8000000>;
        };
};

Replacing calling fdt_getprop_u32() by fit_image_get_entry/load() also
enables support for reading entry/load properties recorded in 64bit format.

cf70553e2c spl: fit: Minimally parse OS properties with FIT_IMAGE_TINY
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
try to append the FDT to ATF (which could clobber adjacent firmware).

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.

Data aborts caused by this were observed on a custom Marvel A388 based system,
where the image was a uboot FIT file. The total size varies depending on the
uboot device tree size, which does not always lead to correct alignment.

152781d464 spl: fit: Allow the board to tell if more images must be loaded from FIT
spl_fit_get_image_name() is used to get the names of the images that the
SPL must load from the FIT. It relies on the content of a property present
in the FIT. The list of images is thus statically defined in the FIT.
With this scheme, it quickly becomes hard to manage combinations of more
than a handful of images.
To address this problem, give the board driver code the opportunity to
add to the list of images. The images from the FIT property are loaded
first, and then the board_get_fit_loadable() is called to get more image
names.

There are many ways the overlay application can fail.
2 of them are probably the most common:
- the application itself failed. Usually this is comes from an unresolved

- DTBO not available in FIT (could be because of a typo)

In both case it is good to be more explicit about the error and at least

6b8b98d54d spl: fit: don't load the firmware twice
When u-boot.img is a FIT image generated automatically by mkimage, the
configuration node has the following structure:
conf-1 {
   description = "k3-am654-base-board";
   firmware = "firmware-1";
   loadables = "firmware-1";
   fdt = "fdt-1";
};

The firmware is referenced twice. Once by the 'firmware' property and
once by the 'loadables' property. Currently this result in the firmware
being loaded twice. This is not a big problem but has an impact on the
boot time.
Fixing it by not loading a loadable image if it is also the firmware image.

b83edfbde9 spl: fit: use U-Boot device tree when FIT image has no device tree
As part of the SPL FIT boot flow, the device tree is appended to U-Boot
proper. The device tree is used to record information on the loadables
to make them available to the SPL framework and U-Boot proper. Depending
on the U-Boot device tree provider, the FIT image might not include a
device tree. Information on the loadables is missing in this case.

When booting via firmware bundled with the FIT image, U-Boot SPL loads
the firmware binary and U-Boot proper before starting the firmware. The
firmware, in turn, is responsible for starting U-Boot proper.
Information on the memory location of the U-Boot proper loadable must be
available to the SPL framework so that it can be passed to the firmware
binary. To support this use case when no device tree is found in the FIT
image, fall back to the U-Boot device tree in this situation.

At the same time, update the comment to remove the note that the
destination address must be aligned to ARCH_DMA_MINALIGN. Alignment is
only required as an intermediate step when reading external data. This
is automatically handled by spl_fit_append_fdt(). After reading the
external data, it is copied to the specified address, which does not
have to be aligned to ARCH_DMA_MINALIGN.

e1eb6ada4e spl: Make image loader infrastructure more universal
The current U-Boot SPL image loader infrastructure is very powerful,
able to initialize and load from a variety of boot media however it
is strongly geared towards loading specific types of images in a very
specific way. To address the need being able to use this infrastructure
to load arbitrary image files go ahead and refactor it as follows:

- Refactor existing spl_mmc_load_image function into superset function,
  accepting additional arguments such as filenames and media load offset
  (same concept can also be applied toother spl_XXX_load_image functions)
- Extend the loader function to "remember" their peripheral initialization
  status so that the init is only done once during the boot process,
- Extend the FIT image loading function to allow skipping the parsing/
  processing of the FIT contents (so that this can be done separately
  in a more customized fashion)
- Populate the SPL_LOAD_IMAGE_METHOD() list with a trampoline function,
  invoking the newly refactored superset functions in a way to maintain
  compatibility with the existing behavior

This refactoring initially covers MMC/SD card loading (RAW and FS-based).

FIT_IMAGE_TINY is used to reduce the size of the SPL by removing os-type
tracking and recording the loadables into the loaded FDT. When this option
is enabled, it is assumed that the next stage firmware is u-boot.
However this does not play well with the SPL_OS_BOOT option that enables
loading different type of next stage firmware, like the OS itself.

When SPL_OS_BOOT is used, do not disable os-tracking. The added footprint
is about 300 Bytes.

e246bfcfe2 SPL: Add HAB image authentication to FIT
Introduce two board level callback functions to FIT image loading process, and
a SPL_FIT_FOUND flag to differentiate FIT image or RAW image.

Implement functions in imx common SPL codes to call HAB funtion
to authenticate the FIT image. Generally, we have to sign multiple regions
in FIT image:
1. Sign FIT FDT data (configuration)
2. Sign FIT external data (Sub-images)

Because the CSF supports to sign multiple memory blocks, so that we can use one
signature to cover all regions in FIT image and only authenticate once.
The authentication should be done after the entire FIT image is loaded into
memory including all sub-images.
We use "-p" option to generate FIT image to reserve a space for FIT IVT
and FIT CSF, also this help to fix the offset of the external data (u-boot-nodtb.bin,
ATF, u-boot DTB).

The signed FIT image layout is as below:
--------------------------------------------------
|     |     |     |   |           |     |        |
| FIT | FIT | FIT |   | U-BOOT    | ATF | U-BOOT |
| FDT | IVT | CSF |   | nodtb.bin |     |   DTB  |
|     |     |     |   |           |     |        |

There shouldn't be a need to call private spl_load_fpga_image function

If there is missing loading bistream by chunks it should be done via
fpga framework instead of having private hooks.
Also spl_load_fpga_image() weak function is not used anywhere and
opening a way for not reviewed hacks out of mainline U-Boot is not the
