Enable the support for boot image header version 3 and 4
using abootimg command.
In order to use version 3 or 4:
1- Vendor boot image address should be given to abootimg cmd.
abootimg addr $1 $vendor_boot_load_addr
2- "ramdisk_addr_r" env variable (ramdisk address) should be set to host
the ramdisk : generic ramdisk + vendor ramdisk
Replace "struct andr_boot_img_hdr_v0*" by "void *" in
some functions since v3 and v4 are now supported as well.

Signed-off-by: Simon Glass <sjg@chromium.org>
As discussed previously [1,2], the source command is not safe to use with
verified boot unless there is a key with required = "images" (which has its
own problems). This is because if such a key is absent, signatures are
verified but not required. It is assumed that configuration nodes will
provide the signature. Because the source command does not use
configurations to determine the image to source, effectively no
verification takes place.
To address this, allow specifying configuration nodes. We use the same
syntax as the bootm command (helpfully provided for us by fit_parse_conf).
By default, we first try the default config and then the default image. To
force using a config, # must be present in the command (e.g. `source
$loadaddr#my-conf`). For convenience, the config may be omitted, just like
the address may be (e.g. `source \#`). This also works for images
(`source :` behaves exactly like `source` currently does).

Several different firmware users have repetitive code to extract the
firmware data from a FIT. Add some helper functions to reduce the amount
of repetition. fit_conf_get_prop_node (eventually) calls
fdt_check_node_offset_, so we can avoid an explicit if. In general, this
version avoids printing on error because the callers are typically
library functions, and because the FIT code generally has (debug)
prints of its own. One difference in these helpers is that they use
fit_image_get_data_and_size instead of fit_image_get_data, as the former
handles external data correctly.

A big part is the DM pinctrl driver, which allows us to get rid of quite
some custom pinmux code and make the whole port much more robust. Many
thanks to Samuel for that nice contribution! There are some more or less
cosmetic warnings about missing clocks right now, I will send the trivial
fixes for that later.
Another big chunk is the mkimage upgrade, which adds RISC-V and TOC0
(secure images) support. Both features are unused at the moment, but I
have an always-secure board that will use that once the DT lands in the
kernel.
On top of those big things we have some smaller fixes, improving the
I2C DM support, fixing some H6/H616 early clock setup and improving the
eMMC boot partition support.
The gitlab CI completed successfully, including the build test for all
161 sunxi boards. I also boot tested on a A64, A20, H3, H6, and F1C100
board. USB, SD card, eMMC, and Ethernet all work there (where applicable).
Most Allwinner sunxi SoCs have separate boot ROMs in non-secure and
secure mode. The "non-secure" or "normal" boot ROM (NBROM) uses the
existing sunxi_egon image type. The secure boot ROM (SBROM) uses a
completely different image type, known as TOC0.
A TOC0 image is composed of a header and two or more items. One item
is the firmware binary. The others form a chain linking the firmware
signature to the root-of-trust public key (ROTPK), which has its hash
burned in the SoC's eFuses. Signatures are made using RSA-2048 + SHA256.
The pseudo-ASN.1 structure is manually assembled; this is done to work
around bugs/quirks in the boot ROM, which vary between SoCs. This TOC0
implementation has been verified to work with the A50, A64, H5, H6,
and H616 SBROMs, and it may work with other SoCs.

Add a stage pre-load that could
check or modify an image.
For the moment, only a header with a signature is
supported. This header has the following format:
- magic : 4 bytes
- version : 4 bytes
- header size : 4 bytes
- image size : 4 bytes
- offset image signature : 4 bytes
- flags : 4 bytes
- reserved0 : 4 bytes
- reserved1 : 4 bytes
- sha256 of the image signature : 32 bytes
- signature of the first 64 bytes : n bytes
- image signature : n bytes
- padding : up to header size
The stage uses a node /image/pre-load/sig to
get some informations:
- algo-name (mandatory) : name of the algo used to sign
- padding-name : name of padding used to sign
- signature-size : size of the signature (in the header)
- mandatory : set to yes if this sig is mandatory
- public-key (madatory) : value of the public key
Before running the image, the stage pre-load checks
the signature provided in the header.
This is an initial support, later we could add the
support of:
- ciphering
- uncompressing
- ...
