2022-12-06sandbox: Rework how SDL is enabled / disabledTom Rini1-1/+1
Given that we can use Kconfig logic directly to see if we have a program available on the host or not, change from passing NO_SDL to instead controlling CONFIG_SANDBOX_SDL in Kconfig directly. Introduce CONFIG_HOST_HAS_SDL as the way to test for sdl2-config and default CONFIG_SANDBOX_SDL on if we have that, or not.

2022-09-02Makefile: Allow LTO to be disabled for a buildSimon Glass1-0/+17
LTO (Link-Time Optimisation) is an very useful feature which can significantly reduce the size of U-Boot binaries. So far it has been made available for selected ARM boards and sandbox. However, incremental builds are much slower when LTO is used. For example, an incremental build of sandbox takes 2.1 seconds on my machine, but 6.7 seconds with LTO enabled. Add a NO_LTO parameter to the build, similar to NO_SDL, so it can be disabled during development if needed, for faster builds. Add some documentation about LTO while we are here.

2021-10-19Makefile: Only build dtc if neededSimon Glass1-0/+21
At present U-Boot always builds dtc if CONFIG_OF_CONTROL is defined, even when DTC is provided. The built dtc is not actually used, so this is a waste of time. Update the Makefile logic to build dtc only if one is not provided to the build with the DTC variable. Add documentation to explain this. This saves about 3.5 seconds of elapsed time on a clean build of sandbox_spl for me. Signed-off-by: Simon Glass <sjg@chromium.org>
