Thomas, All,
On 2020-03-18 21:50 +0100, Thomas Petazzoni spake thusly:
> Some ATF configurations, such as the ones for the STM32MP1 processor
> family, require DTC during the build as Device Tree files are
> used. Without dtc, the build fails:
>
> /bin/sh: 1: dtc: not found
> dtc version too old (), you need at least version 1.4.4
> plat/st/stm32mp1/platform.mk:239: recipe for target 'check_dtc_version' failed
> make[1]: *** [check_dtc_version] Error 1
>
> To solve this, this commit implements a
> BR2_TARGET_ARM_TRUSTED_FIRMWARE_NEEDS_DTC option, in a way that mimics
> the BR2_TARGET_UBOOT_NEEDS_DTC option we already have for the U-Boot
> package.

Applied to master, thanks.
As discused on IRC, if this trend continues, we could/should switch to
depending on the host package if it is enabled, rather than add yet more
such _NEEDS_STUFF options...
