This series implements ECDSA signature verification for FIT images.
The ECDSA code itself is taken from the Kernel. Currently only supported
way to specify a ECDSA key is to compile it into the binary using
CONFIG_CRYPTO_PUBLIC_KEYS, taking it from a device tree is not yet
supported.
Since v2 this series unifies the way public keys are passed to barebox.
We now have a single Kconfig option which takes a list of public keys,
which can be either RSA or ECDSA keys.
Changes since v3:
- add patch to remove unnecessary dependencies from public-keys.h
- add commit message to "crypto: Makefile: make simpler"
Changes since v2:
- fix endianess problems when ECDSA keys are built for a machine with
different endianess
- add struct public_key as a container for different key types
- make FIT image code use generic public key functions
- drop ECDSA dts snippet support (not needed, doesn't work)
- pass NULL to EVP_PKEY_get_utf8_string_param()
Sascha Hauer (16):
