Thanks.  You're right about the depend.  Didn't notice because I have
the dependency installed on my machine.

..of course I was looking in atf-rockchip/ when I checked to see if it
had been committed yet :)

I'll fix the dep/V=1.

I would prefer to import in sysutils/arm-trusted-firmware, we can
split to subpackages if adding support for further SoCs, but that
seems a better "umbrella" directory name.

Please add the following (first needed to build rk3399/drivers/m0,
second so we can see compiler command lines):

BUILD_DEPENDS+= devel/arm-none-eabi/gcc-linaro,arm)
MAKE_FLAGS+= V=1

Then it's OK sthen.

Committed that way.

Right.  The HiSilicon and MediaTek SoCs seem to be high-performance
SoCs like the Rockchip ones.  Xilinx ZyncMP is somewhat interesting
because it combines ARMv8 cores with an FPGA.

Would be good if the Marvell stuff was merged.  But I'm not holding my
breath.

For some of the Freescale/NXP the trusted firmware is part of U-Boot.

You should still go ahead with the atf-allwinner port.

I don't see a reason to use ATF for the rpi3 at this moment.

"arm-trusted-firmware" would match the repository name and seems a
better fit. Maybe expand the DESCR otherwise looks good.

At the moment there is
https://github.com/ARM-software/arm-trusted-firmware/tree/master/plat
arm (juno/vfp)
hisilicon
mediatek
tegra
qemu
rockchip
unipher
zynqmp

maybe some of the other vendor forks will get merged one day?
https://github.com/MarvellEmbeddedProcessors/atf-marvell
https://github.com/renesas-rcar/arm-trusted-firmware

like some others were?

I also felt that this should be a general port for multiple boards, like
we build u-boot.  So for now this will only build the rockchip boards,
but it's still using the "generic" upstream source code.

ARM Trusted Firmware for RK3399

[Mark Kettenis]

Here is a port for ARM Trusted Firmware 1.4 that builds firmware for
the Rockchip RK3399.  I anticipate that this port will build firmware
for other ARMv8 Rockchip SoCs as well; there is code for the RK3328
and RK3368 in the tree as well.  So this installs the firmware as
rk3399-bl31.elf instead of just bl31.elf.

There is support for other SoCs as well.  We currently don't support
any of those though.  There is some qemu code as well that I haven't
looked into.  So maybe this should be a general ATF port?  Since there
already is a port named "atf", I would rename this one to
"arm-trusted-firmware".

Note that the Allwinner ATF is built from different source code, so it
can't easily be included in a general ATF port.

Thoughts?
