Ralf Schlatterbeck 0068611b4d Implement localtime
Now we manage a timezone and daylight-savings aware version of
localtime. We parse UNIX timezone strings. The default (active after the
first call to localtime or localtime_r) is CET/CEST, the timezone of
Europe/Vienna. The wallclock-time osd-example demonstrates how to set a
different timezone via the timezone resource.

Note: After startup no timezone is set. So in this state querying the
timezone resource will return an empty string. After first call to
localtime (if not timezone has been set via the timezone resource) a
query to timezone will return the default timezone string for CET/CEST.

The string returned by the localtime and utc timezones now also includes
the timezone name.

New fields tm_gmtoff and tm_zone were added to the tm structure. These
are available in BSD systems and when setting special compiler
definitions on Linux.

Note: the timezone offset information in the tm structure (tm_gmtoff)
as well as in the tz structure returned by gettimeofday (tz_minuteswest)
may be wrong sign, this code is largely untested.

Add generic AES functions that should be able to support all the modes

address from the driver structure.

Michael LeMay f85654a82f x86, galileo: Add UEFI support
This patch adds support for optionally building EFI binaries in
addition to Multiboot ELF binaries.  It includes a script,
build_uefi.sh, that downloads tool and library sources from the EDK II
project, builds the GenFw tool that is used to create UEFI binaries,
and creates a makefile that is included from the main x86 common
makefile and enables UEFI support in the Contiki build system.  If the
script is not run prior to building Contiki, then an informational
message will be displayed with instructions for running build_uefi.sh
if UEFI support is desired.  This patch also adds the path to the
auto-generated makefile to .gitignore.

This patch modifies the linker script for the Intel Quark X1000 to
account for the output file section offsets and alignment expectations
of the EDK II GenFw project.

This patch also adds a newlib patch to remove the weak symbol
attribute from floating point stdio support routines.  See
<newlib>/newlib/README for an explanation of how the newlib developers
intended for _printf_float and _scanf_float to be linked.  Newlib
declares them as weak symbols with the intention that developers would
force them to be linked only when needed using a linker command line
option.  However, some but not all Contiki programs require them, so
we cannot simply always include or exclude them.  Instead, we remove
the weak symbol attributes and rely on the linker to automatically
determine whether or not they should be linked.  This avoids an issue
in which weak symbols were undefined in the intermediate DLL generated
as part of the UEFI build process.  That resulted in the GenFw program
emitting "ERROR 3000" messages when it encountered relocations
referencing such an undefined symbol.

Finally, this patch updates README.md to both make some revisions to
account for the UART support introduced in previous patches as well as
to provide instructions for using the UEFI support.

Michael LeMay b915e7d5e3 galileo: Omit exception handling unwind tables
This patch modifies the newlib and Contiki C and C++ compiler flags to
omit exception handling unwind tables (see
http://wiki.dwarfstd.org/index.php?title=Exception_Handling).
Removing these tables saves space in debug builds and has not caused
any readily-apparent functional changes.

Here is the size listing for an example program built without this
patch:
   text	   data	    bss	    dec	    hex	filename
  76002	   1508	  21224	  98734	  181ae	all-timers.galileo

Here is the size listing for the same program with this patch:
   text	   data	    bss	    dec	    hex	filename
  72918	   1508	  21224	  95650	  175a2	all-timers.galileo

The primary motivation for this patch is to help enable UEFI support.
The .eh_frame and .eh_frame_hdr sections that are otherwise generated
are treated as code sections by the EDK2 GenFw program, since they are
read-only alloc sections.  They get grouped with the actual code
sections, ahead of the data sections.  This perturbs symbols and
complicates debugging.

Michael LeMay 38206e3980 galileo: Add Ethernet support
This patch adds support for Ethernet to the Intel Galileo port.  It
uses the Intel Quark X1000 Ethernet driver.  It initializes the first
Ethernet interface and starts some common network services.  By
default, it uses the following addresses:
 - Host: 192.0.2.2
 - Netmask: 255.255.255.0
 - Default gateway: 192.0.2.1
 - DNS server: (same as default gateway)
These settings can be changed by editing eth-conf.c.

Michael LeMay abeed93da5 x86: Add driver for Intel Quark X1000 built-in Ethernet
This patch adds a simple, space-efficient driver for the Ethernet
interface built into the Intel Quark X1000.  It only allocates a
single packet descriptor for each of the transmit and receive
directions, computes checksums on the CPU, and enables
store-and-forward mode for both transmit and receive directions.

Ricardo de Almeida Gonzaga 77327181e0 galileo: Add GPIO interrupt example
This patch introduces an example application to demonstrate how to use
GPIO driver APIs to manipulate interrupt pins.

The application uses default galileo pinmux initialization and sets
the GPIO 5 (IO2) as output pin and GPIO 6 (IO3) as interrupt. It toggles
the output pin stat at every half second in order to emulate an interrupt.
This triggers an interrupt and the application callback is called.

Ricardo de Almeida Gonzaga 93c7988069 x86: Add Galileo pinmux support
This patch adds the galileo-pinmux.c and galileo-pinmux.h files,
which support access to pinmux configuration through a function
interface.

This is not 100% supported yet due to some pinmux paths
need Quark X1000 GPIO (legacy and non-legacy) configurations.

After we finish to implement Quark X1000 GPIO driver we'll add
support for this.

Ricardo de Almeida Gonzaga 781375f1d1 x86: Add PCA9685 support
This patch adds pwm-pca9685.c and pwm-pca9685.h files,
which support access to I2C-based PCA9685 PWM controller
configuration register through a function interface.

The PCA9685 is an I2C-bus controlled 16-channel LED controller
optimized for Red/Green/Blue/Amber (RGBA) color backlighting
applications. Each LED output has its own 12-bit resolution
(4096 steps) fixed frequency individual PWM controller that
operates at a programmable frequency from a typical of 24 Hz to
1526 Hz with a duty cycle that is adjustable from 0 % to 100 %
to allow the LED to be set to a specific brightness value.
More about PCA9685 can be found in its datasheet[1].

This driver is needed in order to configure Galileo pinmux.

Ricardo de Almeida Gonzaga 495dcd659a x86: Add PCAL9535A support
This patch adds gpio-pcal9535a.c and gpio-pcal9535a.h files,
which support access to I2C-based PCAL9535A GPIO controller
configuration register through a function interface.

The PCAL9535A is a low-voltage 16-bit GPIO expander with interrupt
and reset for I2C-bus/SMBus applications. It contains the PCA9535
register set of four pairs of 8-bit Configuration, Input, Output,
and Polarity Inversion registers, and additionally, the PCAL9535A has
Agile I/O, which are additional features specifically designed to
enhance the I/O. More about PCAL9535A can be found in its datasheet[1].

This driver is needed in order to configure Galileo pinmux.
