TX492x is 32-bit (/proc/cpuinfo says mips1/mips2/mips3), TX493x is 64-bit.
As Debian dropped support for mips3 and older, I'm stuck at a Jessie nfsroot.

In personal conversations with technical people, I call myself a hacker. But
when I'm talking to journalists I just say "programmer" or something like that.
