binman: Convert Image to a subclass of Entry
When support for sections (and thus hierarchical images) was added to
binman, the decision was made to create a new Section class which could
be used by both Image and an Entry_section class. The decision between
using inheritance and composition was tricky to make, but in the end it
was decided that Image was different enough from Entry that it made sense
to put the implementation of sections in an entirely separate class. It
also has the advantage that core Image code does have to rely on an entry
class in the etype directory.
This work was mostly completed in commit:
8f1da50ccc "binman: Refactor much of the image code into 'section'
As a result of this, the Section class has its own version of things like
offset and size and these must be kept in sync with the parent
Entry_section class in some cases.
In the last year it has become apparent that the cost of keeping things in
sync is larger than expected, since more and more code wants to access
these properties.
An alternative approach, previously considered and rejected, now seems
better.
Adjust Image to be a subclass of Entry_section. Move the code from Section
(in bsection.py) to Entry_section and delete Section. Update all tests
accordingly.
This requires substantial changes to Image. Overall the changes reduce
code size by about 240 lines. While much of that is just boilerplate from
Section, there are quite a few functions in Entry_section which now do not
need to be overiden from Entry. This suggests the change is beneficial
even without further functionality being added.
A side benefit is that the properties of sections are now consistent with
other entries. This fixes a problem in testListCmd() where some properties
are missing for sections.
Unfortunately this is a very large commit since it is not feasible to do
the migration piecemeal. Given the substantial tests available and the
100% code coverage of binman, we should be able to do this safely.

An example of this is with a compressed device tree, where the values
of the device tree change in SetCalculatedProperties() or
ProcessEntryContents(). While the device tree itself does not change size,
since placeholders for any new properties have already bee added by
AddMissingProperties(), we cannot predict the size of the device tree
after compression. If a value changes from 0 to 0x1234 (say), then the
compressed device tree may expand.
As a first step towards supporting this, make ProcessContentsUpdate()

always True (since otherwise binman raises an error), but later patches
will adjust this.

env: am57xx: Implement A/B boot process
Add support for A/B boot process on AM57xx based boards:
1. Define 'slot_suffix' variable (using 'ab_select' command)
2. Extend 'emmc_android_boot' boot command (add commands for A/B boot
process)
'ab_select' command is used to decide which slot should be used for
booting up. A/B metadata resides in 'misc' partition.
To activate the A/B boot process, the following config options must be
set:
CONFIG_ANDROID_AB=y
CONFIG_CMD_AB_SELECT=y
For successful A/B boot, the corresponding A/B infrastructure must be
involved on Android side [1] (including mounting system as root), and
disk must be partitioned accordingly.
When A/B boot is enabled, there are some known limitations currently
exist (not related to A/B patches, need to be implemented later):
1. The 'Verified Boot' sequence is not supported
2. dev path to system partition (system_a or system_b) is passed via
'bootargs' as 'root=' argument like 'root=/dev/mmcblk1p12', but
further we'll need to rework it with respect to dm-verity
requirements [2]
In case when A/B partitions are not present in system (and A/B boot is
enabled), boot up process will be terminated and next message will be
shown:
"boot_a(b) partition not found"

cmd: bcb: Use strcmp() instead of strncmp() for string literals
Quote from https://patchwork.ozlabs.org/patch/
1104244/#
2210814:
----------8<-----------
strncmp() is chosen for the sake of paranoid/defensive programming.
Indeed, strncmp() is not really needed when comparing a variable
with a string literal. We expect strcmp() to behave safely even if the
string variable is not NUL-terminated.
In the same scenario, Linux v5.2-rc7 uses both strcmp() and strncmp(),
but the frequency of strcmp() is higher:
$ git --version
git version 2.22.0
$ (Linux 5.2-rc7) git grep -En 'strncmp\([^"]*"[[:alnum:]]+"' | wc -l
1066
$ (Linux 5.2-rc7) git grep -En 'strcmp\([^"]*"[[:alnum:]]+"' | wc -l
1968
A quick "strcmp vs strncmp" object size test shows that strcmp()
generates smaller memory footprint (gcc-8, x86_64):
$ (U-Boot) size cmd/bcb-strncmp.o cmd/bcb-strcmp.o
text data bss dec hex filename
3373 400 2048 5821 16bd cmd/bcb-strncmp.o
3314 400 2048 5762 1682 cmd/bcb-strcmp.o
So, overall, I agree to use strcmp() whenever variables are compared
with string literals.

image: android: allow to wrap uImage into the Android boot image
This allows to use any available compression format with Android boot image
Since not all available compression formats have a magic number we should
explicitly specify type of compression.
For this purpose using uImage format becomes very useful, as this format is
well-known by the community and mkimage tool is already available.
Usage example:
mkimage -A ARM64 -T kernel -C lzma -d Image.lzma out/kernel
At this moment only -C option is handled, but specifying -A and -T options
are recommended for compatibility reasons in the future.
Kernel that compressed with LZ4 can be already used without wrapping into
the uImage, but I recommend wrapping it into the uImage in order to avoid
situations when by some mistake legacy LZ4 is used, that is interpreted as
raw Image and causes CPU to enter Exception Handler without providing any
meaningful explanation to the user.

For example, in most CI environments this U-Boot command for automatic

where 0xf is "userdata" partition. But the number of "userdata"
partition can be changed any time, when partition table is changed.
