Hello Tom,
for what reason it's not supported?

I'm finding that very useful for debugging.

Perhaps try -Og

--Sean

Only a few issues with conditional compilation breaks it.

Also this issue reproducible if -DDEBUG=1 is used.

Hello guys!

I think the CI verification job for u-boot patches should be updated to include 
CFLAGS like -O0
Because I'm not able to build u-boot for Raspberry Pi (or to another board) 
with -O0

Here the commands how to quickly reprodice the problem:
    export ARCH=arm64
    export CROSS_COMPILE=aarch64-linux-gnueabi-
    export KCFLAGS=-O0
    make rpi_4_defconfig
    make -j$(nproc)

I've attached part of the build log to this email.

You can't build a functional U-Boot with optimization globally disabled,
it's just not supported.
