[U-Boot] [PATCH] IDE: Don't assume there are always two devices per bus

Some SATA controllers can operate in an IDE compatible mode (e.g. mvsata) but will only ever have a single device per bus.

This allows the upcoming DNS323 port to properly identify and use a drive on both SATA interfaces. --- include/ide.h | 3 ++- 1 files changed, 2 insertions(+), 1 deletions(-)
