No need to worry, it mostly just works. Apparently, I-pipe already
covers the whole Cortex-A series with its unified timers, clocks, and
interrupt controllers. Well, with the exception of SoCs that have
additional interrupt controllers - like the NVIDIA Tegra124, which I'm
currently looking at for other purposes.

"Mostly" because sshd is dying for unknown reasons. Same rootfs, same
emulator but newer kernel without I-pipe, and it works fine. One after
the other.

BTW, I noticed that LPAE build is broken. Trivial to fix (missing
argument to cpu_switch_mm), but maybe there is more behind it as it was
not used so far. Anything mm-related that one has to look at carefully
on ARM(v7)?
