Hi U-boot Maintainers,
I want to upstream a new SoC named RK3399 from Rockchip which is AARCH64/ARMv8, we need to support Arm Trust Firmware base on U-boot.
Right now we are using a miniloader(just like SPL in U-boot) to load ATF/U-boot, and PC jump from miniloader to ATF and then to U-boot(with CPU change to EL2 mode or nsEL1), then U-boot load kernel/rootfs as usual.
The ATF support for RK3399 has already upstream Could you give your opinion on how to support ATF on U-boot upstream? When I asked Simon Glass offline, he suggest if we can build ATF as part of the U-boot build process, perhaps with a script in U-boot tree,
Perhaps something like:
make rk3399_board_defconfig make ./scripts/build-atf-image rk3399_board ^^ new script
In any case, a good README would help.
Thanks, - Kever
