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.
This patch the 'debug' rule to simplify the debugging process. This new
rule runs OpenOCD and gdb with the right parameters. OpenOCD runs in
background and its output will be redirected to a log file in the
application's path called LOG_OPENOCD. Once gdb client is detached,
OpenOCD is terminated.
The 'debug' rule is defined in Makefile.customrules-galileo file (create
by this patch) which is included by the Contiki's buildsystem. So to
debug a Contiki application for Galileo board, run the following command:
$ make TARGET=galileo debug
If you use a gdb front-end, you can define the "GDB" environment variable
and your gdb front-end will be used instead of default gdb. For instance,
if you want to use cgdb front-end, just run the command:
$ make BOARD=galileo debug GDB=cgdb
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.

This patch creates the platform/galileo/bsp directory. This directory
contain all files related to Galileo's Board Support Package (BSP). For
now, the BSP consists of libc and bootloader.
Within the BSP directory, we have the scripts build_newlib.sh and build_
grub.sh. These scripts provide an easy and quick way to build the newlib
and the grub for the Galileo platform.
This commit simplifies the regression test for the doxygen build to
allow only 0 warnings.
Clean doxygen.runlog and doxygen.runerr for clean target
and ignore them in .gitignore.
The .2mg image format contains a header which is missing from our file. So our file is rather a .po image.
I opted to not add the .2mg header as it is only necessary if the metadata it contains differs from the values "guessed" when using the "naked" .po image format. On the other hand there are image file consumers not understanding the .2mg image format.
