Request for Testing:

This patch adds support for around 30 different boards. Most .dts
files support a couple of different models. I don't have any of this
hardware. None of this is tested.

Tested by Ben Peddell [off-list ref] (specifically kirkwood-ds210.dts on DS211j)

Hi Ben

Thanks for testing. I will fix the gpo and send a v2 sometime. I
should also check if there are any more gpo's i have as gpio's.
 

To get running on the stock bootloader, I needed to extend the 
initramfs to fill the entire rd.gz flash partition, configure the 
kernel to use the dtb appended to it, configure it to ignore the 
information passed to it by the bootloader, and add the following 
nodes to the dts:

/chosen {
	linux,initrd-start = <0x800040>;
	linux,initrd-end   = <0x940000>;
};

Do you know why these initrd properties are needed?  There is only one
other board in mainline that requires this. I also wonder what
implications this has. u-boot has the capability of reading the initrd
from disc to RAM and passing its location to the kernel. By hard
coding these values, are we blocking that?

Thanks
