Angus Gratton 904b85e365 secure boot: Ensure mbedTLS enables ECDSA if signatures are checked in app and all ECDSA to be disabled if secure boot is not enabled Previously if ECDSA disabled in config then secure_boot_signatures.c would fail to build (whether or not secure boot was enabled). To avoid breaking apps that might be using the signature scheme with custom OTA without enabling secure boot signatures in config, this change just disables this functionality if unavailable in mbedTLS config.

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.)
