README.hardware: add beagleboard documentation
Document the install and boot process for the Beagleboard xM with provisions for the C4. I need someone with a C4 board to validate the steps.

+Texas Instruments Beagleboard (beagleboard)
+===========================================
+
+The Beagleboard is an ARM Cortex-A8 development board with USB, DVI-D, S-Video,
+2D/3D accelerated graphics, audio, serial, JTAG, and SD/MMC. The xM adds a
+faster CPU, more RAM, an ethernet port, more USB ports, microSD, and removes
+the NAND flash. The beagleboard MACHINE is tested on the following platforms:
+
+ o Beagleboard xM
+
+TODO: need someone with a Beagleboard C4 to verify these instructions.
+
+Due to the lack of NAND on the xM, the install and boot process varies a bit
+between boards. The C4 can run the x-loader and u-boot binaries from NAND or
+the SD, while the xM can only run them from the SD. The following instructions
+apply to both the C4 and the xM, but te C4 can skip step 2 (as noted below),
+and may require modification of the NAND environment.
+
+ 1. Partition and format an SD card:
+ # fdisk -lu /dev/mmcblk0
+
+ Disk /dev/mmcblk0: 3951 MB, 3951034368 bytes
+ 255 heads, 63 sectors/track, 480 cylinders, total 7716864 sectors
+ Units = sectors of 1 * 512 = 512 bytes
+
+ Device Boot Start End Blocks Id System
+ /dev/mmcblk0p1 * 63 144584 72261 c Win95 FAT32 (LBA)
+ /dev/mmcblk0p2 144585 465884 160650 83 Linux
+
+ # mkfs.vfat -F 16 -n "boot" /dev/mmcblk0p1
+ # mke2fs -j -L "root" /dev/mmcblk0p2
+
+ The following assumes the SD card partition 1 and 2 are mounted at
+ /media/boot and /media/root respectively. The files referenced here
+ are made available after the build in build/tmp/deploy/images.
+
+ 2. Install the boot loaders
+ This step can be omitted for the C4 as it can have the x-loader and
+ u-boot installed in NAND.
+
+ # cp MLO-beagleboard /media/boot/MLO
+ # cp u-boot-beagleboard.bin /media/boot/u-boot.bin
+
+ 3. Install the root filesystem
+ # tar x -C /media/root -f poky-image-$IMAGE_TYPE-beagleboard.tar.bz2
+ # tar x -C /media/root -f modules-$KERNEL_VERSION-beagleboard.tgz
+
+ 4. Install the kernel uImage
+ # cp uImage-beagleboard.bin /media/boot/uImage
+
+ 5. Prepare a u-boot script to simplify the boot process
+ The Beagleboard can be made to boot at this point from the u-boot command
+ shell. To automate this process, generate a user.scr script as follows.
+
+ Install uboot-mkimage (from uboot-mkimage on Ubuntu or uboot-tools on Fedora).
+
+ Prepare a script config:
+
+ # (cat << EOF
+ setenv bootcmd 'mmc init; fatload mmc 0:1 0x80300000 uImage; bootm 0x80300000'
+ setenv bootargs 'console=tty0 console=ttyS2,115200n8 root=/dev/mmcblk0p2 rootwait rootfstype=ext3 ro'
+ boot
+ EOF
+ ) > serial-boot.cmd
+ # mkimage -A arm -O linux -T script -C none -a 0 -e 0 -n "Poky Minimal" -d ./serial-boot.cmd ./user.scr
+ # cp user.scr /media/boot
+
+ 6. Unmount the SD partitions and boot the Beagleboard
