dts: add property removal option CONFIG_OF_REMOVE_PROPS

2020-01-28T00:54:20+00:00

This can be used for device tree size reduction similar as
CONFIG_OF_SPL_REMOVE_PROPS option. Some boards must pass the
built-in DTB unchanged to the kernel, thus we may not cut it
down unconditionally. Therefore enable the property removal
list option only if CONFIG_OF_DTB_PROPS_REMOVE is selected.

Add dependencies for MALLOC_F and OF_LIBFDT

2020-01-16T00:50:31+00:00

Some features implicitly depended on MALLOC_F and OF_LIBFDT and would
fail at link-time if these features were not enabled.

dts: Kconfig: Fix help for SPL_OF_CONTROL

2019-10-30T21:48:47+00:00

As initially this feature was implemented as a negative CONFIG and
later it was redesigned to be positive the help text should be
updated to reflect this change.

This commit updates the help text to match the current implementation.

dm: Also remove interrupts property from SPL DT

2019-04-12T02:10:05+00:00

interrupt-parent property is removed already that's why there is no
reason to keep interrupts property if parent doesn't exist.

lib: fdt: Allow LZO and GZIP DT compression in U-Boot

2019-04-09T16:19:10+00:00

Add required Kconfig symbols, Makefile bits and macro fixes in a
few places to support LZO and DT compression in U-Boot. This can
save a lot of space with multi-DTB fitImages.

Revert "Ensure device tree DTS is compiled"

2019-03-22T16:15:15+00:00

This reverts commit 27cb7300ffda7a3f1581f0f5a2d3bfe59b97ad67.

I am not sure if I correctly understood the log of commit 27cb7300ffda
("Ensure device tree DTS is compiled"), but the code-diff looks like
it was trying to solve the missed re-compilation when .dts was modified.

Recently, commit 2737dfe096b6 ("kbuild: make arch-dtbs target PHONY")
fixed the issue in a more correct and more complete way.

Anyway, since the former commit, we see a clumsy log like this:

  make[2]: 'arch/sandbox/dts/sandbox.dtb' is up to date

Another problem is, it created multiple paths to descend into
arch/*/dts/, causing a race in parallel building.

So, let's revert it.

kbuild: make arch-dtbs target PHONY

2019-02-28T19:21:46+00:00

Without this, the arch-dtbs target only gets evaluated when building
U-Boot the first time, not when re-building (incrementally building)
U-Boot. Thus incremental builds ignore changes to DTB files.
