docs: arm: convert docs to ReST and rename to *.rst

Converts ARM the text files to ReST, preparing them to be an
architecture book.

The conversion is actually:
  - add blank lines and identation in order to identify paragraphs;
  - fix tables markups;
  - add some lists markups;
  - mark literal blocks;
  - adjust title markups.

At its new index.rst, let's add a :orphan: while this is not linked to
the main index.rst file, in order to avoid build warnings.

+======
+Brutus
+======
+
+Brutus is an evaluation platform for the SA1100 manufactured by Intel.
+For more details, see:
+
+http://developer.intel.com
+
+To compile for Brutus, you must issue the following commands::
+
+	make brutus_config
+	make config
+	[accept all the defaults]
+	make zImage
+
+The resulting kernel will end up in linux/arch/arm/boot/zImage.  This file
+must be loaded at 0xc0008000 in Brutus's memory and execution started at
+0xc0008000 as well with the value of registers r0 = 0 and r1 = 16 upon
+entry.
+
+But prior to execute the kernel, a ramdisk image must also be loaded in
+memory.  Use memory address 0xd8000000 for this.  Note that the file
+containing the (compressed) ramdisk image must not exceed 4 MB.
+
+Typically, you'll need angelboot to load the kernel.
+The following angelboot.opt file should be used::
+
+	base 0xc0008000
+	entry 0xc0008000
+	r0 0x00000000
+	r1 0x00000010
+	device /dev/ttyS0
+	options "9600 8N1"
+	baud 115200
+	otherfile ramdisk_img.gz
+	otherbase 0xd8000000
+
+Then load the kernel and ramdisk with::
+
+	angelboot -f angelboot.opt zImage
+
+The first Brutus serial port (assumed to be linked to /dev/ttyS0 on your
+host PC) is used by angel to load the kernel and ramdisk image. The serial
+console is provided through the second Brutus serial port. To access it,
+you may use minicom configured with /dev/ttyS1, 9600 baud, 8N1, no flow
+control.
+
+Currently supported
+===================
+
+	- RS232 serial ports
+	- audio output
+	- LCD screen
+	- keyboard
+
+The actual Brutus support may not be complete without extra patches.
+If such patches exist, they should be found from
+ftp.netwinder.org/users/n/nico.
+
+A full PCMCIA support is still missing, although it's possible to hack
+some drivers in order to drive already inserted cards at boot time with
+little modifications.
+
+Any contribution is welcome.
+
+Please send patches to nico@fluxnic.net
+
+Have Fun !
