* aes-constant-ft.c - AES forward tables.

* We need something useful for the initial flash ROM page (4 Ki

|
||||
* upgrade of the firmware, it stays intact.
|

*
|

* We decide to put 3/4 of AES forward tables to fill 3 Ki bytes, as
|

* its useful and it won't change.
|

*
|
||||
* The code was taken from aes.c of PolarSSL version 0.14, and then,
|
||||
* modified to add section names.
|
||||
*
|
||||
* Since this is just a data, it wouldn't be copyright-able, but the
|
||||
* original auther would claim so. Thus, we put original copyright
|
||||
* notice here. It is highly likely that there will be no such a
|
||||
* thing for copyright. Nevertheless, we think that PolarSSL is good
|
||||
* software to address here, and encourage people using it.
