[PATCH v5 0/8] scripts/make_fit: Support ramdisks and faster operations

[Simon Glass]

This series updates 'make image.fit' to support adding a ramdisk to the
FIT, either one provided as a parameter or one created from all the
kernel modules.

It also includes a few performance improvement, so that building a FIT
from ~450MB of kernel/module/devicetree files only takes a few seconds
on a modern machine.

Changes in v5:
- Fix 'use' typo
- Add a new patch to split out module targets into a variable
- Build modules automatically if needed (fix from Nicolas Schier)

Changes in v4:
- Update the commit message
- Provide the list of modules from the Makefile
- Reduce verbosity (don't print every module filename)
- Rename the Makefile variable from 'EXTRA' to 'MAKE_FIT_FLAGS'
- Use an empty FIT_MODULES to disable the feature, instead of '0'
- Make use of the 'modules' dependency to ensure modules are built
- Pass the list of modules to the script

Changes in v3:
- Move the ramdisk chunk into the correct patch
- Add a comment at the top of the file about the -r option
- Count the ramdisk in the total files
- Update the commit message
- Add a way to add built modules into the FIT

Changes in v2:
- Don't compress the ramdisk as it is already compressed
