nrf-squash! [nrf noup] bootutil: Add support for KMU stored ED25519 signature key Will instead use the immutable bootloader key slot IDs if b0 is not enabled, adds a Kconfig which can be used to fall back to the previous slot IDs for previously deployed bootloaders Signed-off-by: Jamie McCrae <[email protected]>
