This is a Marvell Kirkwood machine layer for openembedded-core.

Provides two machine configurations but should be easy to
extend to other Kirkwood platforms (these are currently
identical anyway):

 * Netgear Stora (MS2110): Tested inc SATA, USB, RTC.
 * Sheevaplug: Not yet tested.

Linux kernel is currently 2.6.35-rc1 pulled from Marvell
orion git repository. Patches are applied to add support
for the Netgear MS2110 (NetStora) machine.
	
Netgear Stora patches are from Bryan McGuire's repository:
 http://gitorious.org/openstora/orion-netgear_ms2110.

Angstrom instructions:

 * Add this layer to the "sources" folder and add to 
   bblayers.conf
 * Optionally add Git repo to sources/layers.txt if
   you wish to update automatically from Git.
 * Run "./oebb.sh config <machine>" where machine is
   "netstora" or "sheevaplug".
 * Build an image (e.g. "bitbake console-image").
 * Kernel and rootfs are created in deploy folder.

Boot via TFTP (kernel) and NFS (rootfs):

 * Save u-boot variables (arcNumber valid for NetStora):
   * setenv mainlineLinux yes
   * setenv arcNumber 2743
   * saveenv
 * Set bootargs for NFS mount:
   * Set up NFS server exporting a folder containing rootfs
   * Unpack Angstrom-xxx.tar.gz from deploy/images folder
     into rootfs location (must be done as root).
   * setenv bootargs console=ttyS0,115200 root=/dev/nfs rw 
     nfsroot=$(serverip):/nfs/mount/path
	 ip=$(ipaddr):$(serverip):::DB88FXX81:eth0:none
 * Boot kernel via TFTP:
   * Place uImage-<machine>.bin from deploy/images folder
     (e.g. uImage-netstora.bin) into TFTP root.
   * tftpboot 0x800000 uImage-netstora.bin
   * bootm 0x800000

Boot kernel and rootfs from flash (applies to NetStora):

 * Save u-boot variables (arcNumber valid for NetStora):
   * setenv mainlineLinux yes
   * setenv arcNumber 2743
   * saveenva
 * Build an image/rootfs with the mtd-utils package.
 * Boot the kernel/rootfs via TFTP/NFS as described above.
 * Copy the kernel and rootfs .ubi image to TFTP server root.
 * From a serial/SSH terminal:
   * TFTP the kernel and flash to /dev/mtd1:
     * cd /tmp
     * tftp -g -r uImage-netstora.bin 10.4.50.5
	 * flash_eraseall /dev/mtd1
	 * nandwrite -p /dev/mtd1 /tmp/uImage-netstora.bin
   * TFTP the .ubi image and flash to /dev/mtd2:
     * cd /tmp
     * tftp -g -r rootfs.ubi 10.4.50.5
	 * ubiformat /dev/mtd2 -y -f /tmp/rootfs.ubi
	 * ubiattach /dev/ubi_ctrl -m 2
	 * mkdir /mnt/ubifs
	 * mount -t ubifs ubi0 /mnt/ubifs
	 * Check that the rootfs has mounted successfully in /mnt/ubifs.
 * Configure uBoot to boot from flash:
   * setenv bootargs_root ubi.mtd=2,0 root=ubi0 rootfstype=ubifs
   * setenv bootargs_ip ip=10.4.50.165:10.4.50.4:::DB88FXX81:eth0:none
   * setenv bootcmd 'nand read.e 0x800000 0x100000 0x300000; setenv bootargs $(console) $(bootargs_root) $(bootargs_ip); bootm 0x800000'
   * saveenv
   * Reboot and check it runs, or run immediately using 'run bootcmd'.
