Other architectures are supporting the uImage format used by barebox's 'bootm'
command. x86 does'nt. So, we need a special command to be able to boot the
x86 specific bzImage format.

This is a low level disk drive communication driver. It uses the real mode
BIOS found on most x86 platforms, to read and write sectors. Used by the
generic disk driver.

This code uses the always (hopefully) existing PIT device to get the time
reference for barebox.

This code adds a generic x86 platform, enabling barebox to act as a
bootloader like 'GRUB'. Very minimalistic, yet. Supports only a serial console
and is tested with QEMU only.

These functions are special: They are running in the 16 bit real mode world
to bring up barebox on an x86 box.

Add some generic required code to make barebox work on x86.
Note: Resetting the CPU is unfinished yet. I need some ideas how to reset
this kind of architecture gracefully.

Add architecture header files. Some of these files are empty, they only must
exists to make the build system happy.
