If you mean 'why use cmd_ide rather than the Marvell sata driver also 
posted recently', I have expressed my opinion there: 
<http://article.gmane.org/gmane.comp.boot-loaders.u-boot/80702>.

If you mean 'why not make this a standalone driver, e.g. 
driver/net/mvsata_ide.{ch} under a configuration option 
CONFIG_MVSATA_IDE' -- why not, but it would basically be empty of 
'driving' functionality (this is handled by cmd_ide) and would only 
provide initialization code, subject to board options (e.g. 
CONFIG_MVSATA_IDE_ENABLE_PORT{0,1}).

Will do.

Will fix this.

Thanks Prafulla for your feedback.
