imxtools/sbtools: switch SHA1 implementation to Crypto++

2017-01-16T18:59:28+00:00

The current implementation was custom and super slow. Since we use Crypto++
anyway, we might as well get use a good implementation.

imxtools/sbtools: switch AES implementation to Crypto++

2017-01-16T18:59:26+00:00

Instead of having our own copy of the AES code, use a good library to do that.
Crypto++ is well-maintained, supports a lot of ciphers, works on many OSes, and
is optimized for many architectures.

imxtools/sbtools: rework cryptography

2017-01-16T18:58:24+00:00

It was a mess, a mix of crypto_* and cbc_mac calls. I made everything call crypto
functions, and also separate key setup from cryptographic operations, this will
be useful to speed up the code in the upcoming commits. Drop support for "usbotp"
key, since the crypto code for that was never mainlined and we can always get the
keys from a device as long as we have code execution (using the DCP debug registers).

imxtools: rework key/IV overriding logic

2017-01-16T18:50:25+00:00

The overriding of the IV and real key should be the exception, there is no
need to manually set them to false.

mkimxboot: add NWZ-E380 firmware 1.00.200

mkimxboot: implement firmware unpatching

2017-01-02T20:43:51+00:00

imxtools: completely rework patching logic to prepare unpatching

2017-01-02T20:43:10+00:00

The old code was working but a mess to maintain. The new code is cleaner
and always simpler handling of all the different options. Extraction of the
OF is no longer a standalone function but just one particular output type.
This commit prepares the ground for firmware "unpatching" (aka OF extraction
from patched OF). The patching code itself did not change so this commit
should still produce the exact same images as before.
