* Some Cleanup.
* Patch by Richard Woodruff, 10 Jan 2005:
Update support for OMAP2420 (ARM11) and H4 board:
o clean up and add new types to H4 memory probe code.
o fix to work with internal boot.
o added PRCM config III operation.
o fix marginal flash timings.
o add revison ATAG usage.
o enable voltage scaling at power chip.
o fix compile error for i2c.
* Fix network problem (error when receiving multiple ARP packets)
