rsa: add sha256-rsa2048 algorithm
based on patch from andreas@oetken.name: http://patchwork.ozlabs.org/patch/294318/ commit message: I currently need support for rsa-sha256 signatures in u-boot and found out that the code for signatures is not very generic. Thus adding of different hash-algorithms for rsa-signatures is not easy to do without copy-pasting the rsa-code. I attached a patch for how I think it could be better and included support for rsa-sha256. This is a fast first shot. aditionally work: - removed checkpatch warnings - removed compiler warnings - rebased against current head Signed-off-by: Heiko Schocher <hs@denx.de> Cc: andreas@oetken.name Cc: Simon Glass <sjg@chromium.org>
