An FDT map is an entry which holds a full description of the image
entries, in FDT format. It can be discovered using the magic string at
its start. Tools can locate and read this entry to find out what entries
are in the image and where each entry is located.

Quite a few tests will use a real device tree and need it updated with the
binman metadata. Add a helper function for this.

The current test for the 'entry' module is a bit convoluted since it has
to import the module multiple times. It also relies on ordering, in that
test1EntryNoImportLib() must run before test2EntryImportLib() if they are
running in the same Python process.
This is unreliable since neither the ordering of tests nor the process
that they run in is defined.
Fix this by always reloading the entry in these two tests. Also add a
check that the expected value of have_importlib is obtained.
This corrects a code-coverage problem in the 'entry' module on some
systems.

A feature of CBFS is that it allows files to be positioned at particular
offset (as with binman in general). This is useful to support
execute-in-place (XIP) code, since this may not be relocatable.
Add a new cbfs-offset property to control this.

When there is lots of open space in a CBFS it is normally padded with
'empty' files so that sequentially scanning the CBFS can skip from one to
the next without a break.

Add support for putting CBFSs (Coreboot Filesystems) in an image. This

Coreboot uses a simple flash-based filesystem called Coreboot Filesystem
(CBFS) to organise files used during boot. This allows files to be named
and their position in the flash to be set. It has special features for
dealing with x86 devices which typically memory-map their SPI flash to the
top of 32-bit address space and need a 'boot block' ending there.
Create a library to help create and read CBFS files. This includes a
writer class, a reader class and associated other helpers. Only a subset
of features are currently supported.

Sometimes when debugging tests it is useful to keep the input and output
directories so they can be examined later. Add an option for this and
update the binman tests to support it. This affects both the test class
and the tearDown() function called after each test.

At present the -v flag is ignored with tests, so that (for example) -v2
does not have any effect. Update binman to pass this flag through to tests
so that they work just like running binman normally, except in a few
special cases where we are actually testing behaviour with different
levels of verbosity.

Add utility functions to compress and decompress using lz4 and lzma
algorithms. In the latter case these use the legacy lzma support favoured
by coreboot's CBFS.
No tests are provided as these functions will be tested by the CBFS
tests in a separate patch.

At present text entries use an indirect method to specify the text to use,
with a label pointing to the text itself.
Allow the text to be directly written into the node. This is more
convenient in cases where the text is constant.

At present this function always sets both the offset and the size of
entries. But in some cases we want to set only one or the other, for
example with the forthcoming ifwi entry, where we only set the offset.
Update the function to handle this.

At present having a descriptor means that there is an ME (Intel
Management Engine) entry as well. The descriptor provides the ME location
and assumes that it is present.
For some SoCs this is not true. Before providing the location of a
potentially non-existent entry, check if it is present.
Update the comment in the ME entry also.

At present binman requires that the Intel descriptor has an explicit
offset. Generally this is 0 since the descriptor is at the start of the
image. Add a default to handle this, so users don't need to specify the
offset.

Some Intel SoCs from about 2016 boot using an internal microcontroller via
an 'IFWI' image. This is a special format which can hold firmware images.
In U-Boot's case it holds u-boot-tpl.bin.
Add this tool, taken from coreboot, so that we can build bootable images
on apollolake SoCs.
This tool itself has no tests. Some amount of coverage will be provided by
the binman tests that use it, so enable building the tool on sandbox.

The generic code in common/spl/spl.c allows TPL/SPL banners to be
silenced by unsetting CONFIG_TPL_BANNER_PRINT or CONFIG_SPL_BANNER_PRINT
respectively. However, arch/arm/mach-rockchip/tpl.c prints this banner
unconditionally.
Fix the rockchip-specific tpl.c so that the TPL banner depends on
CONFIG_TPL_BANNER_PRINT in the same way as the generic code.

If CONFIG_DEBUG_UART is set but CONFIG_TPL_SERIAL_SUPPORT is not, the
serial output should be available in SPL and full U-Boot, but not built
in TPL. However, the rockchip tpl.c instead fails to compile with
undefined references to the debug UART.
Instead, initialise the debug UART and print the TPL banner only if both
CONFIG_DEBUG_UART and CONFIG_TPL_SERIAL_SUPPORT are set.
