[PATCH v9 0/6] scripts/make_fit: Support ramdisks and faster operations

[Simon Glass <sjg@chromium.org>]

This series updates 'make image.fit' to support adding a ramdisk to the
FIT, provided as a parameter.

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.

For this version I have dropped inclusion of built modules, as there is
still more discussion to happen in that area.

Changes in v9:
- Rename the variable to FIT_EXTRA_ARGS

Changes in v8:
- Drop erroneous line 'kbuild: Allow adding modules into the FIT ...'

Changes in v7:
- Add a note about the " -> ' change
- Add a new patch with the MAKE_FIT_FLAGS change
- Mention xz as well, in the commit message
- Drop patch 'scripts/make_fit: Provide a way to add built modules'
- Drop patch 'kbuild: Split out module targets into a variable'
- Drop patch 'kbuild: Allow adding modules into the FIT ramdisk'

Changes in v6:
- Drop the load address for ramdisk, as it is not needed
- Bring back the ramdisk 'compression' property, set to 'none'

Changes in v5:
- Fix 'use' typo

Changes in v4:
- Update the commit message

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

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