Subject: Using CONFIG_PHYSICAL_START

Hi Kumar,

Quick question about the support for booting at a non-zero base address 
(as committed here: 
http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=37dd2badcfcec35f5e21a0926968d77a404f03c3). 
  Is booting from a non-zero address as simple as changing 
"CONFIG_PHYSICAL_START" (assuming it meets the alignment constraints, of 
course)?

For example, I want to boot from a non-zero address on the P1022DS.  I 
should just be able to change "CONFIG_PHYSICAL_START" to, say, 
0x08000000, and it should work, right?  Any other bits that need to be 
done (i.e. U-Boot or device tree magic)?
