the SATA/IDE/etc... layers seem to go against the u-boot policy when it comes to initialization. in other words, if support for them is enabled, then they are unconditionally initialized in board code (see ide_init / sata_initialize in lib_*/board.c:board_init_r). am i missing something or should these init functions be delayed until the sata/ide/whatever functions need them ? or should they be made explicit like some commands where you first have to do "sata init" before you can access the device ?
this bugs me most because normally u-boot starts up nice & fast, but now that we've added SATA support, there's an annoying second or 3 pause while the disk is probed ... -mike
