[POWERPC] Add device tree utility functions to zImage 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.

[POWERPC] bootwrapper: Fix array handling in dt_xlate_reg(). This fixes a few bugs in how dt_xlate_reg() handles address arrays: 1. copy_val() was copying into the wrong end of the array, resulting in random stack garbage at the other end. 2. dt_xlate_reg() was getting the result from the wrong end of the array. 3. add_reg() and sub_reg() were treating the arrays as little-endian rather than big-endian. 4. add_reg() only returned an error on a carry out of the entire array, rather than out of the naddr portion. 5. The requested reg resource was checked to see if it exceeded the size of the reg property, but not to see if it exceeded the size of the buffer.

[POWERPC] bootwrapper: Add dt_xlate_reg(), and use it to find serial registers. 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>

[POWERPC] bootwrapper: Fix array handling in dt_xlate_reg(). This fixes a few bugs in how dt_xlate_reg() handles address arrays: 1. copy_val() was copying into the wrong end of the array, resulting in random stack garbage at the other end. 2. dt_xlate_reg() was getting the result from the wrong end of the array. 3. add_reg() and sub_reg() were treating the arrays as little-endian rather than big-endian. 4. add_reg() only returned an error on a carry out of the entire array, rather than out of the naddr portion. 5. The requested reg resource was checked to see if it exceeded the size of the reg property, but not to see if it exceeded the size of the buffer.

[POWERPC] Add dt_xlate_addr() to bootwrapper dt_xlate_reg() looks up the 'reg' property in the specified node to get the address and size to translate.
