[U-Boot] 2010.09-rc1 SD/MMC tested on Atmel AT91SAM9G45EKES - works

[Reinhard Meyer]

  Dear William C. Landolina,

> Reinhard - FYI, your 2010.09-rc1 SD/MMC patches work on an Atmel 9G45 evaluation kit.  I customized the board and configuration files following the directions in README.atmel_mci and everything works as expected.  I included the console output from a test boot below in case there is some information in the debugging messages that is of interest.

Seems the card does not understand the CMD8 (Voltage supplied)

The function that sets clock and blocksize is repeatedly called by the common MMC
framework, one might want to make that output debug only. Fot the time being, however,
its good to see that the calculated clock is less than what the card can handle.
What clocks does you system use? Xtal/PLL/PBI?
