arch/x86: add placeholders for Intel64 headers Use different headers for kernel_arch_{func,thread}.h when in CONFIG_X86_LONGMODE, and add placeholders for Intel64 versions. Signed-off-by: Charles E. Youse <charles.youse@intel.com>

arch/x86: initial Intel64 bootstrap framework This patch adds basic build infrastructure, definitions, a linker script, etc. to use the Zephyr and 0.10.1 SDK to build a 64-bit ELF binary suitable for use with GRUB to minimally bootstrap an Apollo Lake (e.g., UpSquared) board. The resulting binary can hardly be called a Zephyr kernel as it is lacking most of the glue logic, but it is a starting point to flesh those out in the x86 tree. The "kernel" builds with a few harmless warnings, both with GCC from the Zephyr SDK and with ICC (which is currently being worked on in a separate branch). These warnings are either related to pointer size differences (since this is an LP64 build) and/or dummy functions that will be replaced with working versions shortly. Signed-off-by: Charles E.

arch/x86: initial Intel64 support First "complete" version of Intel64 support for x86. Compilation of apps for supported boards (read: up_squared) with CONFIG_X86_LONGMODE=y is now working. Booting, device drivers, interrupts, scheduling, etc. appear to be functioning properly. Beware that this is ALHPA quality, not ready for production use, but the port has advanced far enough that it's time to start working through the test suite and samples, fleshing out any missing features, and squashing bugs.
