Linux won't even boot on sun4u machines
Hasn't been updated in awhile, but https://fedoraproject.org/wiki/Architectures/SPARC I've also had gentoo and ubuntu running on ultra 5 workstations...
I was reading that the ARM chips support Big and Little endian. Is this selected by the OS or by the firmware? Also does this make a difference for compiled software, such as a binary for a Linux application?
It depends on which ARM... Older armv4, you could load a BE or LE kernel (your userland would have to match the kernel)... For newer versions, you're mostly stuck with LE.
