commit: https://git.buildroot.net/buildroot/commit/?id=fbed118ed20f2701425720f510b02b3ad1345a2e
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master
Some ATF configurations, require a pre-built bare metal toolchain to
build some platforms which host cortex-m series core, for instance
rockchip rk3399 has a cortex-m0 core. Without a pre-built bare metal
toolchain, the build fails:
make[3]: arm-none-eabi-gcc: Command not found
To solve this, this commit implements a
BR2_TARGET_ARM_TRUSTED_FIRMWARE_NEEDS_ARM32_TOOLCHAIN
option. Platforms which have such requirement should enable this
config option.
