2007-04-13[POWERPC] bootwrapper: Add dt_xlate_reg(), and use it to find serial registers.Scott Wood
dt_xlate_reg() uses the ranges properties of a node's parentage to find the absolute physical address of the node's registers. The ns16550 driver uses this when no virtual-reg property is found. Signed-off-by: Scott Wood <scottwood@freescale.com> Signed-off-by: Paul Mackerras <paulus@samba.org>
2007-04-13[POWERPC] Add device tree utility functions to zImageDavid Gibson
This patch adds a library of useful device tree manipulation functions to the zImage library, for use by platform code. These functions are based on the hooks already in dt_ops, so they're not dependent on a particular device tree implementation. This patch also slightly streamlines the code in main.c using these new functions. This is a consolidation of my work in this area with Scott Wood's patches to a very similar end.
