Move the warning to an error as we have been promising would happen in

Oh. This has broken my U-Boot build/test system. I guess it's entirely my
fault for interpreting the "2018.01" warning as "you'll need to fix this in
Jan 2018", not "you'll need to fix this as soon as development starts for
2018.01":-(

I'm tagging v2018.01-rc1 later today, so I think this is about the time
to enforce the warning.

Is there a reason for requiring such an extremely new gcc, as opposed to
simply something not ancient? For example, no LTS version of Ubuntu packages
a compiler that's new enough to build U-Boot now:-(

There's always the Free Electrons toolchains, as well as Linaro.  And
yes, we've been having size problems and having to play various games to

Yes, I have the AT91 based smartweb board, for which the SPL have to fit
into 4k sram (is in my weekly tbot builds).

allow for older gcc versions to still fit things in.  GCC-6 is where
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=54303 was resolved and we
get a lot of space saved, and a number of platforms simply won't work
with older.

Just looked at:

http://toolchains.free-electrons.com/

for example the stable toolchains for arm are gcc 5.4.0 based.

Ok, there is the "bleeding-edge" ... gcc 7.2.0 based...

Hmm.. linaro has 7.2.0 in its latest release ... so, currently only
linaro toolchain can be used for compiling U-Boot ?

setup the tbot tests with linaro toolchain:
https://releases.linaro.org/components/toolchain/binaries/7.2-2017.11/arm-linux-gnueabi/

Ok, build for corvus board works, see:

http://xeidos.ddns.net/tests/test_db_auslesen.php#528

but for the smartweb board I get:

  LD      spl/drivers/built-in.o
  LD      spl/u-boot-spl
arm-linux-gnueabi-ld.bfd: u-boot-spl section `.u_boot_list' will not fit in

This build worked last week with gcc 4.9.2, see
