* Implement generalised RSA public exponents for verified bootMichael van der Westhuizen2014-08-09-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | Remove the verified boot limitation that only allows a single RSA public exponent of 65537 (F4). This change allows use with existing PKI infrastructure and has been tested with HSM-based PKI. Change the configuration OF tree format to store the RSA public exponent as a 64 bit integer and implement backward compatibility for verified boot configuration trees without this extra field. Parameterise vboot_test.sh to test different public exponents. Mathematics and other hard work by Andrew Bott. Tested with the following public exponents: 3, 5, 17, 257, 39981, 50457, 65537 and 4294967297.

* includes: move openssl headers to include/u-bootJeroen Hofstee2014-06-19-0/+117
commit 18b06652cd "tools: include u-boot version of sha256.h" unconditionally forced the sha256.h from u-boot to be used for tools instead of the host version. This is fragile though as it will also include the host version. Therefore move it to include/u-boot to join u-boot/md5.h etc which were renamed for the same reason. cc: Simon Glass <sjg@chromium.org> Signed-off-by: Jeroen Hofstee <jeroen@myspectrum.nl>
