galileo: Initial support for Intel Galileo Platform This patch adds the initial support for Intel Galileo Platform. It contains the minimum set of code required to boot a dummy Contiki image. For Galileo initial support, we implemented a linker script, a minimal bootstrap code, a set of stubbed functions required by newlib, and a very simple main() function. Moreover, we also define some header files and macros required by Contiki. To build applications for this platform you should first build newlib (in case it wasn't already built). To build newlib you can run the following command: $ platform/galileo/bsp/libc/build_newlib.sh Once newlib is built, you can build applications. To build applications for Galileo platform you should set TARGET variable to 'galileo'. For instance, building the hello-world application should look like this: $ cd examples/hello-world/ && make TARGET=galileo This will generate the 'hello-world.galileo' file which is a multiboot- compliant [1] ELF image. This image can be booted by any multiboot- complaint bootloader such as Grub. Finally, this patch should be used as a guideline to add the initial support for others platforms based on x86 SoCs.

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.

galileo: Add support for Clock module This patch adds support for Contiki's clock module. All functions from core/sys/clock.h are implemented, except clock_set_seconds() and clock_ delay_usec(). The CLOCK_CONF_SECOND macro is set to 128. This value seems to be good enough since several platforms used it. Finally, we use the RTC driver to track the number of ticks from the system clock.

typedef unsigned long clock_time_t;
galileo: Support for rtimer library This patch adds support for rtimer library on Galileo's platform. We use the PIT to implement the rtimer platform dependent functionalities. We chose the PIT for mainly two reason: I) its configuration is very simple II) it has a high frequency which provides us a good clock resolution (requirement from rtimer library). Since we keep track of the number of ticks in software, we define rtimer_clock_t type as uint64_t. This gives us a good amount of time til the variable overflows. For instance, a 32-bit type would overflow in about one hour for high clock resolution (~ 1us). The rtimer clock frequency (RTIMER_ARCH_SECOND) is setup to 1 kHz. There is no technical matter regarding this value. It is just an initial guess. Just for the record, we might want to use HPET in future to implement the rtimer library since it seems to be more appropriate. The reason why we don't use it at this moment is that, in order to configure it, we need support for ACPI 2.0 which we don't. Once we have use-cases for the rtimer library we'll probably replace PIT by HPET or any other timer more suitable for the job.
