* 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)
