Should we garbage-collect some of the other nommu platforms where
we're here? Some of them are just as stale:
1. xtensa nommu has does not compile in mainline and as far as I can
tell never did
(there was https://github.com/jcmvbkbc/linux-xtensa/tree/xtensa-5.6-esp32,
which
worked at some point, but I don't think there was enough interest
to get in merged)
Hmm, I build and test nommu_kc705_defconfig in my test system.
What toolchain do you use for this? Max already pointed out my mistake
regarding xtensa, which I thought does not build at all, but just needs
a toolchain specific to the cpu.
Home-built using buildroot. I have three different xtensa toolchains
(de212, dc232b, and dc233c). The toolchain for kc705_nommu needs the
de212 overlay; I think Max pointed to to the information needed
to build the compiler. Buildroot has the "XTENSA_OVERLAY_FILE"
option to specify the compiler overlay file for the target.
