+\`configure' configures libcryptech 0.1 to adapt to many kinds of systems.
+
+Usage: $0 [OPTION]... [VAR=VALUE]...
+
+To assign environment variables (e.g., CC, CFLAGS...), specify them as
+VAR=VALUE. See below for descriptions of some of the useful variables.
+
+Defaults for the options are specified in brackets.
+
+Configuration:
+ -h, --help display this help and exit
+ --help=short display options specific to this package
+ --help=recursive display the short help of all the included packages
+ -V, --version display version information and exit
+ -q, --quiet, --silent do not print \`checking ...' messages
+ --cache-file=FILE cache test results in FILE [disabled]
+ -C, --config-cache alias for \`--cache-file=config.cache'
+ -n, --no-create do not create output files
+ --srcdir=DIR find the sources in DIR [configure dir or \`..']
+
+Installation directories:
+ --prefix=PREFIX install architecture-independent files in PREFIX
+ [$ac_default_prefix]
+ --exec-prefix=EPREFIX install architecture-dependent files in EPREFIX
+ [PREFIX]
+
+By default, \`make install' will install all the files in
+\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc. You can specify
+an installation prefix other than \`$ac_default_prefix' using \`--prefix',
+for instance \`--prefix=\$HOME'.
+
+For better control, use the options below.
+
+Fine tuning of the installation directories:
+ --bindir=DIR user executables [EPREFIX/bin]
+ --sbindir=DIR system admin executables [EPREFIX/sbin]
+ --libexecdir=DIR program executables [EPREFIX/libexec]
+ --sysconfdir=DIR read-only single-machine data [PREFIX/etc]
+ --sharedstatedir=DIR modifiable architecture-independent data [PREFIX/com]
+ --localstatedir=DIR modifiable single-machine data [PREFIX/var]
+ --libdir=DIR object code libraries [EPREFIX/lib]
+ --includedir=DIR C header files [PREFIX/include]
+ --oldincludedir=DIR C header files for non-gcc [/usr/include]
+ --datarootdir=DIR read-only arch.-independent data root [PREFIX/share]
+ --datadir=DIR read-only architecture-independent data [DATAROOTDIR]
+ --infodir=DIR info documentation [DATAROOTDIR/info]
+ --localedir=DIR locale-dependent data [DATAROOTDIR/locale]
+ --mandir=DIR man documentation [DATAROOTDIR/man]
+ --docdir=DIR documentation root [DATAROOTDIR/doc/libcryptech]
+ --htmldir=DIR html documentation [DOCDIR]

+/*
+
+Each Cryptech core has a set of 4-byte registers, which are accessed
+through a 16-bit address. The address space is divided as follows:
+ 3 bits segment selector | up to 8 segments
+ 5 bits core selector | up to 32 cores/segment (see note below)
+ 8 bits register selector | up to 256 registers/core (see modexp below)
+
+i.e, the address is structured as:
+sss ccccc rrrrrrrr
+
+The I2C and UART communication channels use this 16-bit address format
+directly in their read and write commands.
+
+The EIM communications channel translates this 16-bit address into a
+32-bit memory-mapped address in the range 0x08000000..807FFFF:
+00001000000000 sss 0 ccccc rrrrrrrr 00
+
+EIM, as implemented on the Novena, uses a 19-bit address space:
+ Bits 18..16 are the semgent selector.
+ Bits 15..10 are the core selector.
+ Bits 9..2 are the register selector.
+ Bits 1..0 are zero, because reads and writes are always word aligned.
+
+Note that EIM can support 64 cores per segment, but we sacrifice one bit
+in order to map it into a 16-bit address space.
