lib: rsa: generate additional parameters for public key

2020-03-12T12:20:39+00:00

In the current implementation of FIT_SIGNATURE, five parameters for
a RSA public key are required while only two of them are essential.
(See rsa-mod-exp.h and uImage.FIT/signature.txt)
This is a result of considering relatively limited computer power
and resources on embedded systems, while such a assumption may not
be quite practical for other use cases.

In this patch, added is a function, rsa_gen_key_prop(), which will
generate additional parameters for other uses, in particular
UEFI secure boot, on the fly.

Note: the current code uses some "big number" routines from BearSSL
for the calculation.

xilinx: zynq: Add support to secure images

2018-07-19T08:49:54+00:00

This patch basically adds two new commands for loadig secure
images.
1. zynq rsa adds support to load secure image which can be both
   authenticated or encrypted or both authenticated and encrypted
   image in xilinx bootimage(BOOT.bin) format.
2. zynq aes command adds support to decrypt and load encrypted
   image back to DDR as per destination address. The image has
   to be encrypted using xilinx bootgen tool and to get only the
   encrypted image from tool use -split option while invoking
   bootgen.

SPDX: Convert all of our single license tags to Linux Kernel style

2018-05-07T13:34:12+00:00

When U-Boot started using SPDX tags we were among the early adopters and
there weren't a lot of other examples to borrow from.  So we picked the
area of the file that usually had a full license text and replaced it
with an appropriate SPDX-License-Identifier: entry.  Since then, the
Linux Kernel has adopted SPDX tags and they place it as the very first
line in a file (except where shebangs are used, then it's second line)
and with slightly different comment styles than us.

In part due to community overlap, in part due to better tag visibility
and in part for other minor reasons, switch over to that style.

This commit changes all instances where we have a single declared
license in the tag as both the before and after are identical in tag
contents.  There's also a few places where I found we did not have a tag
and have introduced one.

rsa: Split the rsa-verify to separate the modular exponentiation

2015-01-30T00:09:58+00:00

Public exponentiation which is required in rsa verify functionality is
tightly integrated with verification code in rsa_verify.c. The patch
splits the file into twp separating the modular exponentiation.

1. rsa-verify.c
- The file parses device tree keys node to fill a keyprop structure.
The keyprop structure can then be converted to implementation specific
format.
(struct rsa_pub_key for sw implementation)
- The parsed device tree node is then passed to a generic rsa_mod_exp
function.

2. rsa-mod-exp.c
Move the software specific functions related to modular exponentiation
from rsa-verify.c to this file.
