History
Angus Gratton f0d74b1c64 bootloader: Ensure bootloader never returns to caller 
* Fixes some "noreturn" functions in bootloader utils which did return (causing fatal CPU
  exceptions).
* Marks bootloader entry as "noreturn", preventing "user code done" from stalling boot
  Partial fix for https://github.com/espressif/esp-idf/issues/1814 TW20016
  (Comprehensive fix for this issue will be enabling WDT during bootloader, coming shortly.)

Bootloader Support Component
============================

Overview
--------

"Bootloader support" contains APIs which are used by the bootloader but are also needed for the main app.

Code in this component needs to be aware of being executed in a bootloader environment (no RTOS available, BOOTLOADER_BUILD macro set) or in an esp-idf app environment (RTOS running, need locking support.)
