--- Comment #1 from André H. nerv@dawncrow.de --- Awesome, seems like we don't need to mess with the kernel! And it seems gcc already supports that: https://gcc.gnu.org/onlinedocs/gcc-4.2.1/gcc/Code-Gen-Options.html -ffixed-x18 (found here: http://lists.denx.de/pipermail/u-boot/2013-September/162241.html) And we can initialize it similar to what we do on ARM
