Simon Glass <sjg@chromium.org> says:

This includes various patches towards implementing the VBE abrec
bootmeth in U-Boot. It mostly focuses on SPL tweaks and adjusting what
fatures are available in VPL.

help
Normally with the SPL framework a legacy image is generated as part
of the build. This contains U-Boot along with information as to
where it should be loaded. This option instead enables generation
of a FIT (Flat Image Tree) which provides more flexibility. In
particular it can handle selecting from multiple device tree
and passing the correct one to U-Boot.
This path has the following limitations:
1. "loadables" images, other than FDTs, which do not have a "load"
property will not be loaded. This limitation also applies to FPGA
images with the correct "compatible" string.
2. For FPGA images, the supported "compatible" list is in the
doc/uImage.FIT/source_file_format.txt.
3. FDTs are only loaded for images with an "os" property of "u-boot".
"linux" images are also supported with Falcon boot mode.

Enables CRC8 support in TPL. This is not normally required. CRC8 is
a simple and fast checksumming algorithm which does a bytewise
