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: correctly read unencrypted images in raw mode

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.

imxtools: rework sb file production

2017-01-16T18:49:07+00:00

The old code had some annoying way of dealing with padding by adding explicit
instructions to the stream, which is 1) ugly 2) not in par with freescale
tools. The trick, which this new version implements, is to put the useful length
of the section in the section header, and the actual (with padding) length in
the boot tag. This way the tools can just ignore padding instruction by
reading the section header, and the bootloader can still load the image because
it uses the boot tags.
Also correctly handle the case where the first section does not start right
after the header (there is a bug in freescale tools for this case by the way).
There is an ambiguity in the way the padding instructions should be encrypted:
the bootloader should logically treat them as regular instruction of the section
stream, but it appears the freescale tools do not generate them as part of the
stream and instead encrypt them like boot tags, which is stupid because there
is no way the bootloader could decrypt them, and anyway we don't care because
the bootloader doesn't decrypt them at all.

imxtools: various fixes for Windows

2017-01-07T14:52:33+00:00

Don't use colors since the terminal doesn't support it. Also packing is broken
on MinGW so use #pragma pack when compiling for windows, this is also supported
by MSCV.

imxtools: move firmware read/write to library

2017-01-07T14:52:33+00:00

Split the ugly firmware read/write into a API function and a much simplified code.
Also the code can now report progress.

imxtools/scsitools: move stmp scsi api to its own file

2017-01-07T14:52:33+00:00

No code modification code, just moving code around.
