binman: Allow writing a map file when something goes wrong

2018-09-29T17:49:35+00:00

When we get a problem like overlapping regions it is sometimes hard to
figure what what is going on. At present we don't write the map file in
this case. However the file does provide useful information.

Catch any packing errors and write a map file (if enabled with -m) to aid
debugging.

binman: Correct fmap output on x86

2018-09-29T17:49:35+00:00

Normally x86 platforms use the end-at-4gb option. This currently produces
an FMAP with positions which have a large offset. The use of end-at-4gb is
a useful convenience within binman, but we don't really want to export
a map with these offsets.

Fix this by subtracting the 'skip at start' parameter.

Also put the code which convers names to fmap format, for clarity.

binman: Support hashing entries

2018-09-29T17:49:35+00:00

Sometimesi it us useful to be able to verify the content of entries with
a hash. Add an easy way to do this in binman. The hash information can be
retrieved from the device tree at run time.

binman: Support expanding entries

2018-09-29T17:49:35+00:00

It is useful to have entries which can grow automatically to fill
available space. Add support for this.

binman: Support adding files

2018-09-29T17:49:35+00:00

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.

binman: Support updating all device tree files

2018-09-28T17:09:01+00:00

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().

binman: Obtain the list of device trees from the config

2018-09-28T17:09:01+00:00

We always have a device tree for U-Boot proper. But we may also have one
for SPL and TPL. Add a new Entry method to find out what DTs an entry
has, and use that list when updating DTs.

binman: Centralise device-tree updates within binman

2018-09-28T17:09:01+00:00

At present we have a few calls to device-tree functions in binman and plan
to add more as we add new entry types which need to report their results.

It makes sense to put this code in a central place so that we can make
sure all device trees are updated. At present we only have U-Boot proper,
but plan to add SPL and TPL too.

binman: Move state information into a new module

2018-09-28T17:09:01+00:00

At present the control module has state information in it, since it is the
primary user of this. But it is a bit odd to have entries and other
modules importing control to obtain this information.

It seems better to have a dedicated state module, which control can use as
well. Create a new module using code from control and update other modules
to use it.

binman: Add an entry method for getting the default filename

2018-09-28T17:09:01+00:00

Various entry implementations provide a way to obtain the default filename
for an entry. But at present there is no base-class implementation for
this function. Add one so that the API is defined.
