Some ARM64 platforms (such as Allwinner A64/H5) have a boot process where U-Boot encapsulates the BL31 part of the ARM trusted firmware. For such platforms, we need to build ATF before U-Boot, and pass a BL31 variable pointing to ATF bl31.bin to the U-Boot build process. This commit introduces a BR2_TARGET_UBOOT_NEEDS_ATF_BL31 variable to achieve this. Signed-off-by: Jagan Teki <jagan@amarulasolutions.com> [Thomas: - Rename option to BR2_TARGET_UBOOT_NEEDS_ATF_BL31 - Drop changes to arm-trusted-firmware.mk, they are taken care of by previous commits. - Improve Config.in help text - Add missing dependency on arm-trusted-firmware when BR2_TARGET_UBOOT_NEEDS_ATF_BL31 is enabled. - Use bl31.bin from $(BINARIES_DIR) instead of taking it from ATF's build dir.] [Peter: depend on toplevel atf option and select bl31 option. Ensure it cannot be enabled together with ARM_TRUSTED_FIRMWARE_UBOOT_AS_BL33 as that would cause circular dependencies] Signed-off-by: Thomas Petazzoni <thomas.petazzoni@free-electrons.com> Tested-by: Jagan Teki <jagan@amarulasolutions.com> Signed-off-by: Peter Korsgaard <peter@korsgaard.com> |
