Move the warning to an error as we have been promising would happen in this release.
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-li...
Ok, build for corvus board works, see:
http://xeidos.ddns.net/tests/test_db_auslesen.php#528
but for the smartweb board I get:

This build worked last week with gcc 4.9.2, see
