[U-Boot-Users] [PATCH libfdt 1/3] Fix errors when CONFIG_OF_LIBFDT is enabled

Several node strings were not correct (trailing slashes and properties in the strings) Added setting of the timebase-frequency (if OF_TBCLK is defined). Added more error printouts.

Please respin, base on top of u-boot-testing (you might create a conflict with another TSEC patch if you don't), and since it applies to cpu/mpc83xx/cpu.c, submit through the mpc83xx tree (i.e. prepend the string 'mpc83xx: ' in your subject, and wait for me to ask Wolfgang to pull).
This seems to have fixed most of the functional issues; thanks for that. Please read linux-2.6/Documentation/CodingStyle if you haven't already. Thank you!

When I wrote it originally, I mistakenly returned -FDT_ERR_NOTFOUND, wanted to make it clear to the next editor that 0 (OK) was intentional.
The ETH* do a set if it exists, do not create if it doesn't exist. Other properties are created if they don't exist. Part of the above comments were to highlight that the different pattern/behavior was intentional.
