* rsa: Allow to directly compile in rsa public keysSascha Hauer2019-10-151-0/+33
| | | | | | | | | | | | | So far we relied on the U-Boot mkimage tool to generate us device tree snippets containing rsa public keys which we then compiled into barebox. Make this easier and allow to directly specify a filename or PKCS#11 URI in Kconfig. With this we no longer need the U-Boot mkimage tool here and no more external steps to prepare device tree snippets. With this rsa public keys can be directly compiled as C structs into barebox which is much more direct than putting it into the device tree. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* rsa: let rsa_of_read_key() return a fully allocated keySascha Hauer2019-10-151-4/+22
| | | | | | | | | | Until now rsa_of_read_key() took a pointer to a key and filled the struct rsa_public_key members with allocated values. So far we have never freed these values. Change rsa_of_read_key() to always return a fully allocated key and provide rsa_key_free() to free it. Let the FIT image code free the key after usage.

Taken from U-Boot and adopted to barebox with little changes. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de> Signed-off-by: Marc Kleine-Budde <mkl@pengutronix.de>
