Got it. Presumably you're saving to on-chip SRAM, not DRAM, even for non-secure
state.
Generic code should care about both space & time too, but in cases where
there's a trade-off between the two there's very clearly a need for SoC

I don't think so. Seems that the device registration for Babbage is
missing, as well as a quirk for the timeout problem. Ho

The goal of the patch is to provide an easy way to find the guilty

I like it. Any chance of flavouring -mcpu= or -mtune= to set the
