Supporting OTA bootloader updates?

[agoode]

Describe your core improvement

There is new functionality enabled by updated bootloader versions on the esp series (sram1_as_iram, rollback support) but this unfortunately requires a serial update. Many of my devices are in annoying-to-reach places, so I would like to be able to update the bootloader via OTA.

I know this is potentially dangerous, but as long as the correct warnings are provided, should save time in most cases and would let me update the bootloader on devices I wouldn't normally bother with. (I am assuming that a failed bootloader OTA would be recoverable with a serial flash, which I have to do anyway in the current situation.)

Current limitations

Currently there is no way for the bootloader on esp devices to be updated over the air.

Technical benefits

Users would be able to enable new features more easily in most cases.
