The compiler.h header defines two macros INCBIN and INCFILE that can be used to include binary files into C sources. This patch fixes a few issues with them: * The .align directive is equivalent to .p2align on some architectures (ARM/AArch64) and to .balign on others (x86). INCBIN previously used .align and now uses .balign for correct alignment. * .align 1 enforces a 2-byte alignment on ARM/AArch64, which caused the _end symbol for the binary to be off by 1 byte in some cases, which the macro previously accounted for (incorrectly). With the correct .balign directive the extra byte is never added, so the size is now correctly computed without the -1 addend. * INCBIN should end in a .previous directive to restore the previous section, since the macro starts with .section.

LK
The LK embedded kernel. An SMP-aware kernel designed for small systems.
See https://github.com/littlekernel/lk for the latest version.
See https://github.com/littlekernel/lk/wiki for documentation.
Builds
To build and test for ARM on linux
- install or build qemu. v2.4 and above is recommended.
- install gcc for embedded arm (see note 1)
- run scripts/do-qemuarm (from the lk directory)
- you should see 'welcome to lk/MP'
This will get you a interactive prompt into LK which is running in qemu arm machine 'virt' emulation. type 'help' for commands.
note 1: for ubuntu: sudo apt-get install gcc-arm-none-eabi or fetch a prebuilt toolchain from http://newos.org/toolchains/arm-eabi-5.3.0-Linux-x86_64.tar.xz
