The PKA drivers and examples were full of include paths missing the
appropriate prefix, or using angle brackets instead of double quotes or
the other way around.

Add generic AES functions that should be able to support all the modes
of operation of the hardware AES crypto engine, i.e. ECB, CBC, CTR,
CBC-MAC, GCM, and CCM.
This makes it possible to easily implement these modes of operation
without duplicating code.

This patch adds support for building the UEFI EDK2 tools on 32-bit
hosts. It also revises the script to support rebuilding the tools
when the script is re-invoked after the EDK2 repository has previously
been downloaded.
This patch refactors the MMIO routines in the GPIO and I2C drivers to
eliminate the base_addr parameter that specifies the MMIO base
address. Instead, just the MMIO routines themselves retrieve the base
address from the driver structure.
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 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.
