[U-Boot] [PATCH v2 00/37] binman: Add CBFS support

[Simon Glass]

CBFS (Coreboot Filesystem) is a simple ROM-based filesystem used for
locating data needed during booting. It has particular features for x86
such as defining a boot block at the top of the ROM image. At run-time,
boot loaders can locate files in the ROM by searching for a header and
magic strings in the ROM.

It is common to have multiple, separate CBFSs in the ROM.

Binman provides its own way of locating data, typically with a device
tree built into the image, or linker symbols when space is short. But it
is useful to be able to create images containing CBFSs with binman, since
it allows all image structure to defined in one place, rather than spread
out over multiple cbfstool invocations, etc.

The approach taken here is to directly create the CBFS in binman rather
than calling out to cbfstool. The latter is quite slow for multiple
invocations and the tool itself has no tests.

Also included is ifwitool lifted from coreboot, which is needed to package
images for Intel apollo lake SoCs. This seems easier than implementing
this functionality in binman.

Tests are provided for new binman functionality, although ifwitool has no
tests and is tested only by invocation from binman.

This series does not support all CBFS features, just raw binaries and Elf
files (called 'stages' in CBFS).

Changes in v2:
- Deal with travis's old lz4 version by skipping tests as necessary
- Install lzma tool in travis
- Skip use of cbfstool in tests if it is not available
