[U-Boot] Adding a new board to U-Boot

[U-Boot] Adding a new board to U-Boot

[Robert Mortimer]

First off I aplogise for top posting. It is common on some of the groups I am in 
You will be glad to know I have registerd our board with the ARM registry 
I have updated my local git repo to reflect the number we were given. 
None of the porting guides I found round the internet seemed to include this step 

Please could you confirm my understanding that the unique reference 
is passed to the loading Linux kernel to allow it to configure it's self for 
the target hardware.

The mach-type number has to be passed by the bootloader to the kernel via the
register r1 in case of ARM based processors atleast.

You can refer to http://www.arm.linux.org.uk/developer/booting.php
and http://www.linux-arm.org/LinuxKernel/LinuxNewPlatformPort for more on this.
