It is useful to be able to quickly locate the FDT map in the image. An
easy way to do this is with a pointer at the start or end of the image.
Add an 'image header' entry, which places a magic number followed by a

image, or at a chosen location.

An FDT map is an entry which holds a full description of the image

Currently binman calculates '_skip_at_start' based on 'end-at-4gb'
property and it is used for x86 images.
For PowerPC mpc85xx based CPU, CONFIG_SYS_TEXT_BASE is the entry
offset of the first entry. It can be 0xeff40000 or 0xfff40000 for
nor flash boot, 0x201000 for sd boot etc, so "_skip_at_start"
should be set to CONFIG_SYS_TEXT_BASE.
'end-at-4gb' property is not applicable where CONFIG_SYS_TEXT_BASE +
Image size != 4gb.

At present each entry has an offset within its parent section. This is

is sometimes necessary to locate an entry within an image, regardless
of which sections it is nested inside.

some documentation for the -u option binman provides, which updates the
device tree with final entry information.
Since the image position is a better symbol to use for the position of
U-Boot as obtained by SPL, update the SPL symbols to use this instead of
offset, which might be incorrect if hierarchical sections are used.

After some thought, I believe there is an unfortunate naming flaw in
binman. Entries have a position and size, but now that we support
hierarchical sections it is unclear whether a position should be an
absolute position within the image, or a relative position within its
parent section.
At present 'position' actually means the relative position. This indicates
a need for an 'image position' for code that wants to find the location of
an entry without having to do calculations back through parents to
discover this image position.
A better name for the current 'position' or 'pos' is 'offset'. It is not
always an absolute position, but it is always an offset from its parent
offset.
It is unfortunate to rename this concept now, 18 months after binman was
introduced. However I believe it is the right thing to do. The impact is
mostly limited to binman itself and a few changes to in-tree users to
binman:
tegra
sunxi
x86
The change makes old binman definitions (e.g. downstream or out-of-tree)
incompatible if they use the 'pos = <...>' property. Later work will
adjust binman to generate an error when it is used.

When U-Boot started using SPDX tags we were among the early adopters and
there weren't a lot of other examples to borrow from. So we picked the
area of the file that usually had a full license text and replaced it
with an appropriate SPDX-License-Identifier: entry. Since then, the
Linux Kernel has adopted SPDX tags and they place it as the very first
line in a file (except where shebangs are used, then it's second line)
and with slightly different comment styles than us.
In part due to community overlap, in part due to better tag visibility
and in part for other minor reasons, switch over to that style.
This commit changes all instances where we have a single declared
license in the tag as both the before and after are identical in tag
contents. There's also a few places where I found we did not have a tag
and have introduced one.

Binman construct images consisting of multiple binary files. These files
sometimes need to know (at run timme) where their peers are located. For
example, SPL may want to know where U-Boot is located in the image, so
that it can jump to U-Boot correctly on boot.
In general the positions where the binaries end up after binman has
finished packing them cannot be known at compile time. One reason for
this is that binman does not know the size of the binaries until
everything is compiled, linked and converted to binaries with objcopy.
To make this work, we add a feature to binman which checks each binary
for symbol names starting with '_binman'. These are then decoded to figure
out which entry and property they refer to. Then binman writes the value
of this symbol into the appropriate binary. With this, the symbol will
have the correct value at run time.
Macros are used to make this easier to use. As an example, this declares
a symbol that will access the 'u-boot-spl' entry to find the 'pos' value
(i.e. the position of SPL in the image):
binman_sym_declare(unsigned long, u_boot_spl, pos);
This converts to a symbol called '_binman_u_boot_spl_prop_pos' in any
binary that includes it. Binman then updates the value in that binary,
ensuring that it can be accessed at runtime with:
ulong u_boot_pos = binman_sym(ulong, u_boot_spl, pos);
This assigns the variable u_boot_pos to the position of SPL in the image.
