This patch set adds, tests, and documents support for variable sized cells in
cell arrays. The new syntax is:
property = /bits/ [8|16|32|64] <0x00 0x12>;
So cell arrays of 8, 16, 32, or 64-bits can now be created. No padding is
done on the resulting cell array. So if three 8-bit cells
This utility routine will be used in the variable size cell literal
append code. It is a straightforward adaptation of the fdt32_to_cpu
function.

This function deals with appending integers of various sizes (8, 16
32, and 64 bit currently). It handles endianess conversions. If the
integer will not fit in the requested number of bits of storage it
will have it's high bits ignored.
This patch also rewrites data_append_cell and data_append_a
Cells of size 8, 16, 32, and 64 bits are supported. The new
/bits/ syntax was selected so as to not pollute the reserved
keyword space with uint8/uint16/... type names.
With this patch the following property assignment:
property = /bits/ 16 <0x1234 0x5678 0x0 0x>;
is equivalent to:
Hi Tony, Grant,
Here is the first set of patches to add device-tree support for OMAP3+
platforms.
That series mainly adds a minimal OMAP2+ generic board file for basic
DT support on OMAP2420, OMAP2430, OMAP3, OMAP4 and beyond. The goal is
to remove even the minimal static devices init in order to
Add initial device-tree support for OMAP4 SoC.
This is based on the original panda board patch done by Manju:
http://permalink.gmane.org/gmane.linux.ports.arm.omap/60393
Add the generic GIC interrupt-controller from ARM.
Add an empty "soc" node to contain non memory mapped IPs
(DSP, MPU, IPU...)
Add SoC specific map_io function to be used by the generic DT
board file. This is an intermediate step before having some
generic DT aware map_io function.

Thanks, I'll apply this into cleanup branch and with the related
conversion of board files.
