The hwmod code and data format was originally designed to minimize
boot time and for autogenerated data files. Compactness was traded
for precomputation. Now that the emphasis is on reducing the number
of lines in the OMAP source tree, this trade can be reversed.
This series removes the precomputed "link arrays" from the hwmod data,
and converts the code to register IP blocks by their interconnects,
rather than directly. This results in a significant reduction in
lines of source, at the cost of some additional boot time. The change
also makes it easier to share more IP block data across SoCs.
This series has a dependency on the 'hwmod_data_cleanup_3.4' branch
posted earlier.
This series is also available via git://git.pwsan.com/linux-2.6 in the
"hwmod_remove_link_arrays_cleanup_3.4" branch.
Boot-tested on N800. Boot and suspend-tested on OMAP35xx Beagleboard
and OMAP44xx Pandaboard.
