+
+ This file contains the code for declaring the tables needed to implement
+ AES. The file aesopt.h is assumed to be included before this header file.
+ If there are no global variables, the definitions here can be used to put
+ the AES tables in a structure so that a pointer can then be added to the
+ AES context to pass them to the AES routines that need them.   If this
+ facility is used, the calling program has to ensure that this pointer is
+ managed appropriately.  In particular, the value of the t_dec(in,it) item
+ in the table structure must be set to zero in order to ensure that the
+ tables are initialised. In practice the three code sequences in aeskey.c
+ that control the calls to aes_init() and the aes_init() routine itself will
+ have to be changed for a specific implementation. If global variables are
+ available it will generally be preferable to use them with the precomputed
+ FIXED_TABLES option that uses static global tables.
+
+ The following defines can be used to control the way the tables
+ are defined, initialised and used in embedded environments that
+ require special features for these purposes
+
+    the 't_dec' construction is used to declare fixed table arrays
+    the 't_set' construction is used to set fixed table values
+    the 't_use' construction is used to access fixed table values
+
+    256 byte tables:
+
+        t_xxx(s,box)    => forward S box
+        t_xxx(i,box)    => inverse S box
+
+    256 32-bit word OR 4 x 256 32-bit word tables:
+
+        t_xxx(f,n)      => forward normal round
+        t_xxx(f,l)      => forward last round
+        t_xxx(i,n)      => inverse normal round
+        t_xxx(i,l)      => inverse last round
+        t_xxx(l,s)      => key schedule table
+        t_xxx(i,m)      => key schedule table
