Roll CRC16-CCITT into the hash infrastructure

2018-12-09T01:18:44+00:00

The CRC16-CCITT checksum function is useful for space-constrained
applications (such as obtaining a checksum across a 2KBit or 4KBit
EEPROM) in boot applications. It has not been accessible from boot
scripts until now (due to not having a dedicated command and not being
supported by the hash infrstructure) limiting its applicability
outside of custom commands.

This adds the CRC16-CCITT (poly 0x1021, init 0x0) algorithm to the
list of available hashes and adds a new crc16_ccitt_wd_buf() to make
this possible.

lib: merge CRC16-CCITT into u-boot/crc.h

2018-12-09T01:18:32+00:00

This merges the CRC16-CCITT headers into u-boot/crc.h to prepare for
rolling CRC16 into the hash infrastructure.  Given that CRC8, CRC32
and CRC32-C already have their prototypes in a single header file, it
seems a good idea to also include CRC16-CCITT in the same.

rsa: add support of padding pss

2018-12-03T15:44:10+00:00

We add the support of the padding pss for rsa signature.
This new padding is often recommended instead of pkcs-1.5.

rsa: add a structure for the padding

2018-12-03T15:44:10+00:00

The rsa signature use a padding algorithm. By default, we use the
padding pkcs-1.5. In order to add some new padding algorithm, we
add a padding framework to manage several padding algorithm.
The choice of the padding is done in the file .its.

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.

include: Add a variadic macro to call a callback for all arguments

2017-10-03T01:52:16+00:00

Add a header variadic-macro.h which defines the CALL_MACRO_FOR_EACH marco.

This macro can be used as follows:
  #define TEST(x)
  CALL_MACRO_FOR_EACH(TEST, a, b, c, d)

This will expand to
  TEST(a) TEST(b) TEST(c) TEST(d)

The nice thing is that CALL_MACRO_FOR_EACH is a variadic macro, thus the
number of arguments can vary (although it has an upper limit - in this
implementation 32 arguments).

rsa: Verify RSA padding programatically

2016-11-21T19:07:30+00:00

Padding verification was done against static SHA/RSA pair arrays which
take up a lot of static memory, are mostly 0xff, and cannot be reused
for additional SHA/RSA pairings. The padding can be easily computed
according to PKCS#1v2.1 as:

  EM = 0x00 || 0x01 || PS || 0x00 || T

where PS is (emLen - tLen - 3) octets of 0xff and T is DER encoding
of the hash.

Store DER prefix in checksum_algo and create rsa_verify_padding
function to handle verification of a message for any SHA/RSA pairing.
