Disabling interrupts in bios for serial boot, re-enabling when files are uploaded completely.

[Rajnesh28]

Does anyone have any thoughts on the value of creating a PR that disables interrupts in the bios before it begins serial booting and downloading files via serial? I am afraid that I will press a key in the terminal and cause the transfer to corrupt after spending precious time uploading the files.

I can look into making a PR if you guys think this might be a good idea.

Probably better to enforce policy like this from the tool doing the sending, target then baking it into the remote device.

For example, you could do something like the policy you are describing in litex term. One idea would be to ignore keystrokes other than ^C when serial load is in progress. Higher baud rates also make this process much nicer.
