Here is a series providing a couple of fixes and enhancements on the
SMC driver, among which :

 - support of the segment registers which are needed to set the
   mapping windows of the chips on the AHB bus.
 - command mode support 
 - detection of the best HCLK settings for reads (adapted from pflash)

The full tree can be found here:


Tested on the palmetto, ast2500 evb and witherspoon platforms.
