3679362355 dt/documentation: Fix value format description
Numeric values in dts files can be specified in decimal and hex (the latter
prefixed 0x). The current documentation is updated with this patch to prevent
confusion about what is meant with values without "0x" (previously hex, now
dec).

da6b737b9a x86: Add device tree support
This patch adds minimal support for device tree on x86. The device
tree blob is passed to the kernel via setup_data which requires at
least boot protocol 2.09.

Memory size, restricted memory regions, boot arguments are gathered
the traditional way so things like cmd_line are just here to let the
code compile.

The current plan is use the device tree as an extension and to gather
information which can not be enumerated and would have to be hardcoded
otherwise. This includes things like 
   - which devices are on this I2C/SPI bus?
   - how are the interrupts wired to IO APIC?
   - where could my hpet be?

7211da1778 Revert "dt: add documentation of ARM dt boot interface"
This reverts commit 9830fcd6f6.

The ARM dt support has not been merged yet; this documentation update
was premature.

cf4e5c6e8d dt: Remove obsolete description of powerpc boot interface
32 and 64 bit powerpc support has been merged for a while now, but
the booting-without-of.txt document still describes 32 bit as not
supporting multiplatform, which is no longer true.  This patch fixes
the documentation.

Also remove references to powerpc-specific details outside of section
I in preparation to add details for other architectures.

v3: cleaned up a lot more powerpc-isms and updated text to reflect current
    usage conventions.

d524dac927 dt: Move device tree documentation out of powerpc directory
The device tree is used by more than just PowerPC.  Make the documentation
directory available to all.

v2: reorganized files while moving to create arch and driver specific
    directories.
