Kconfig: Create a new tools menu At present MKIMAGE_DTC_PATH is in the devicetree menu but not within 'devicetree control' since it does not relate to that. As a result it shows up in the top menu. It actually relates to the mkimage tool, so create a new tools menu for it and move it there. Signed-off-by: Simon Glass <sjg@chromium.org>

help
The mkimage host tool will, in order to generate FIT images make
calls to the dtc application in order to create the output. In
some cases the system dtc may not support all required features
and the path to a different version should be given here.
tools: Use a single target-independent config to enable OpenSSL Host tool features, such as mkimage's ability to sign FIT images were enabled or disabled based on the target configuration. However, this misses the point of a target-agnostic host tool. A target's ability to verify FIT signatures is independent of mkimage's ability to create those signatures. In fact, u-boot's build system doesn't sign images. The target code can be successfully built without relying on any ability to sign such code. Conversely, mkimage's ability to sign images does not require that those images will only work on targets which support FIT verification. Linking mkimage cryptographic features to target support for FIT verification is misguided. Without loss of generality, we can say that host features are and should be independent of target features. While we prefer that a host tool always supports the same feature set, we recognize the following - some users prefer to build u-boot without a dependency on OpenSSL. - some distros prefer to ship mkimage without linking to OpenSSL To allow these use cases, introduce a host-only Kconfig which is used to select or deselect libcrypto support. Some mkimage features or some host tools might not be available, but this shouldn't affect the u-boot build. I also considered setting the default of this config based on FIT_SIGNATURE. While it would preserve the old behaviour it's also contrary to the goals of this change. I decided to enable it by default, so that the default build yields the most feature-complete mkimage.

config TOOLS_LIBCRYPTO
bool "Use OpenSSL's libcrypto library for host tools"
default y
help
Cryptographic signature, verification, and encryption of images is
provided by host tools using OpenSSL's libcrypto. Select 'n' here if
you wish to build host tools without OpenSSL. mkimage will not have
the ability to sign images.
This selection does not affect target features, such as runtime FIT
signature verification.
image: Add Kconfig options for FIT in the tools build In preparation for enabling CONFIG_IS_ENABLED() on the host build, add some options to enable the various FIT options expected in these tools. This will ensure that the code builds correctly when CONFIG_TOOLS_xxx is distinct from CONFIG_xxx. Drop some #ifdefs which are immediately unnecessary (many more are in later patches).

image: Use Kconfig to enable CONFIG_FIT_VERBOSE on host Add a host Kconfig for FIT_VERBOSE.

hash: Use Kconfig to enable hashing in host tools and SPL At present when building host tools, we force CONFIG_SHAxxx to be enabled regardless of the board Kconfig setting. This is done in the image.h header file. For SPL we currently just assume the algorithm is desired if U-Boot proper enables it. Clean this up by adding new Kconfig options to enable hashing on the host, relying on CONFIG_IS_ENABLED() to deal with the different builds. Add new SPL Kconfigs for hardware-accelerated hashing, to maintain the current settings. This allows us to drop the image.h code and the I_WANT_MD5 hack.
