Adds a recipe to pull down the prebuilt GCC for compiling on Cortex-R
and Cortex-M processors from ARM. This toolchain is required to build
Arm Trusted Firmware for the Rockchip rk3399 SoC, since it must compile
some firmware for the M0 coprocessor.
can this use mutliconfig ?
This seems then can be avoided
I'm not sure if multiconfig is applicable in this case; This is required
because the same recipe (arm-trusted-firmware) requires 2 different
compilers to be available; the target compiler (aarch64-poky-linux), and
an arm-none-eabi-gcc compiler specifically to compile some M0 firmware
that goes into ATF.
Multiconfig would work (I think), if the recipe only needed one or the
other, but not in this case where it needs both.
right, so question is if this recipe can be effectively two such recipes. If not
then perhaps this solution is ok or perhaps we can just use prebuilts for the M0
It *might* be possible to build it in two passes, but I'd rather not
because its not the way the ATF is intended to be built. The code
currently expects that it can build with the arm-none-eabi-gcc, so
anything thing we do differently is more likely to break. Right now, the
AFT recipe should be pretty easy to maintain; breaking it apart will
make it quite a bit more complicated.
I'd rather have a prebuilt (for now) GCC building some firmware from
source that download a prebuilt firmware image :)
Like I said, long term I'd like to build up the arm-none-eabi-gcc from
gcc-cross in OE-core, I just haven't figured out the best way to do that
yet.
I also looked at building an additional gcc-cross recipe that explicitly
targets arm-none-eabi, but the maintenance was going to be a pain unless
A) the recipe lived in OE-core or B) this layer copied all of the GCC
recipes. Neither of those was appealing at the moment, but I plan on
revisiting it. Even when I did have it in OE-core, I had some trouble
with some manifest warnings, so I'm not quite sure I was doing it correctly.
