Normally when an entry is created, any entry arguments it has are required
to be provided, so it can actually generate its contents correctly.
However when an existing image is read, Entry objects are created for each
of the entries in the image. This happens as part of the process of
reading the image into binman.
In this case we don't need the entry arguments, since we do not intend to
regenerate the entries, or at least not unless requested. So there is no
sense in reporting an error for missing entry arguments.
Add a new property for the Image to handle this case. Update the error
reporting to be conditional on this property.

CROSS_COMPILE = i386-linux-gnu-

When reading subentries of each image, the FIT entry type directly

respective to the beginning of each image. For example, the following

A recent change adjusted the symbol calculation to work on x86 but broke
it for Tegra. In fact this is because they have different needs.
On x86 devices the code is linked to a ROM address and the end-at-4gb
property is used for the image. In this case there is no need to add the
base address of the image, since the base address is already built into
the offset and image-pos properties.
On other devices we must add the base address since the offsets start at
zero.
In addition the base address is currently added to the 'offset' and 'size'
values. It should in fact only be added to 'image-pos', since 'offset' is
relative to its parent and 'size' is not actually an address. This code
should have been adjusted when support for 'image-pos' and 'size' was
added, but it was not.
To correct these problems:
- move the code that handles adding the base address to section.py, which
can check the end-at-4gb property and which property
(offset/size/image-pos) is being read
- add the base address only when needed (only for image-pos and not if the
image uses end-at-4gb)
- add a note to the documentation
- add a separate test to cover x86 behaviour

Sometimes we want to include TPL for x86 platforms, such as when we want
to select between different SPL images (e.g. for Chrome OS verified boot).
Add support for this.

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.
Add new property 'skip-at-start' in Section class so that
'_skip_at_start' can be calculated either based on 'end-at-4gb'
or based on "skip-at-start".
Add a test case to check that 'skip-at-start' and 'end-at-4gb'
property can't be used together.

This property has been changed to 'offset'. To help downstream users who
might still be using 'pos', add a check that this is not used by mistake.

Add support for U-Boot's TPL and TPL device tree. Also fix a few comments
in the other device-tree entries.
