fa1c937832 binman: Don't assume there is an ME region
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.

fe1ae3ecc3 binman: Support ELF files for U-Boot and SPL
For sandbox we want to put ELF files in the image since that is what we
need to execute. Add support for this.

f025363543 binman: Support x86 microcode in TPL
When TPL is used on x86 we may want to program the microcode (at least for
the first CPU) early in boot. Add support for this by refactoring the
existing code to be more generic.

0a98b28b06 binman: Support adding files
In some cases it is useful to add a group of files to the image and be
able to access them at run-time. Of course it is possible to generate
the binman config file with a set of blobs each with a filename. But for
convenience, add an entry type which can do this.

Add required support (for adding nodes and string properties) into the
state module.

83d73c2f7c binman: Support compressed entries
Add support for compressing blob entries. This can help reduce image sizes
for many types of data. It requires that the firmware be able to
decompress the data at run-time.

6ed45ba0a8 binman: Support updating all device tree files
Binman currently supports updating the main device tree with things like
the position of each entry. Extend this support to SPL and TPL as well,
since they may need (a subset of) this information.

Also adjust DTB output files to have a .out extension since this seems
clearer than having a .dtb extension with 'out' in the name somwhere.

Also add a few missing comments and update the DT setup code to use
ReadFile and WriteFile().

a326b495cd binman: Tidy up the vblock entry
At present if there are two vblock entries an image their contents are
written to the same file in the output directory. This prevents checking
the contents of each separately.

Fix this by adding part of the entry path to the filename, and add some
missing comments.

35b384cbe5 binman: Add x86 support for starting TPL
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.

3af8e49cef binman: Add an entry filled with a repeating byte
It is sometimes useful to have an area of the image which is all zeroes,
or all 0xff. This can often be achieved by padding the size of an an
existing entry and setting the pad byte for an entry or image.

But it is useful to have an explicit means of adding blocks of repeating
data to the image. Add a 'fill' entry type to handle this.

Add an entry which can hold an FMAP region as used by flashrom, an
open-source flashing tool used on Linux x86 machines. This provides a
simplified non-hierarchical view of the entries in the image and has a
signature at the start to allow flashrom to find it in the image.
