Going through the BIOS means multiple minutes of waiting for stuff hoping it finally boots, during which time I don't have a workstation to do email or anything else on. I should time the boot but I think it's about 5-10mins (and I'm too scared to reboot just to time it).
On our TX2 server, boot times were 3 minutes, but firmware upgrade (7.0) made it 8 minutes. Turns out this is to do with the DDR tests and here's how to move it back to 3 minutes:

Before UEFI menu there's a message to "press 's' for setup". Do it, then:
CAVM_CN99xx# env set dbg_speed_up_ddr_lvl 1 CAVM_CN99xx# env save
Hope it helps, --renato
It does seem to cut the "BIOS time" down to just under 4mins. Thanks! A full reboot cycle though from hitting "reboot" in my GUI to seeing my GUI logged on again is about 6mins still. The kernel spends something like 30 secs on boot just enumerating CPUs for example. It seems unable to bring up CPUs in parallel...
