Hang after printing "NOTICE: Cold boot"

[brooksbp]

I just did a fresh checkout of the 17.10 branches and flashed the flash-image.bin to SPI ROM on MACCHIATObin board, and am seeing this hang:

BootROM - 2.03
Starting CP-1 IOROM 1.07
Booting from SPI NOR flash 1 (0x32)
Found valid image at boot postion 0x000
lNOTICE:  Starting binary extension

NOTICE:  Cold boot

I suspect it's related to compiling with GCC 7.3.0. Will try with GCC 5.4.0

[brooksbp]

Yes, it boots to U-Boot CLI just fine with GCC 5.4.0. The issue must be with GCC 7.x...

I tested the entire 17.10 release using Linaro GCC toolchain release gcc-linaro-7.2.1-2017.11-x86_64_aarch64-linux-gnu Everything looks OK. Have you created your own cross-toolchain out of sources?

I used the GCC 7.3.0 cross toolchain (aarch64-linux-gnu-gcc, ...) from Debian testing.

Ubuntu 18.04 is at GCC 7.3.0 as well.

[kostapr]

I haven't tried to use Debian cross toolchain. I planned to switch to GCC 7.3.0 once it get released by Linaro. I suggest you to use the lasted available Linaro AARCH64 binary releases for your builds.

[afaerber]

I ran into the same issue with openSUSE GCC 7.3.1: Distro toolchains are starting to default to PIE. You explicitly need to disable PIE for your target code via -fno-PIE or similar compiler options. Upstream TF-A's detection code is still incomplete though, it only works when the compiler was configured with --enable-default-pie whereas openSUSE uses a defaults file that can globally be installed and removed without reconfiguring GCC.
