Hi,
I just upgraded my Arch Linux system to the latest arm-none-eabi-gcc version which is "7.1.0-1" (from 6.3.1-1). After I did this I ran into two issues. First, u-boot no longer links. I get several linker errors [1]. Secondly, if I build a Linux kernel v4.10 image with this compiler it won't boot. It hangs at "Starting kernel...". Reverting back to v6.3 of gcc fixes both issues. Don't know if this is an issue with gcc or with the gcc package (from community. I did not build it myself) that is built for Arch Linux.
