[Buildroot] [pull request] Pull request for branch bootloaders-cleanup

[Thomas Petazzoni <thomas.petazzoni@free-electrons.com>]

Hello,

Here is my first set of cleanup patches for 2010.08. This set tries to
cleanup the bootloader compilation code.

In short:

 * Move bootloader code from target/ to boot/ (new directory)

 * Add support for the Barebox bootloader

 * Simplify how U-Boot is handled, with less configuration options

 * Drop support for Yaboot

 * Bump syslinux and fix various build issues

 * Cleanup everywhere

 * Mark grub2 as BROKEN: it wasn't working, it still doesn't build
   properly.

The following configurations do work for me :

 * U-Boot ARM at91sam9263ek + AT91bootstrap for the same board

 * Barebox ARM at91sam9263ek

 * Grub x86

 * Syslinux x86

 * Pxelinux x86

 * Barebox PowerPC pcm030

 * U-Boot PowerPC barco

As usual, there are certainly remaining issues, and possible further
cleanups. Don't hesitate to let me know about your ideas.

Cheers,

Thomas
