U-Boot can detect if an IDE device is present or not. If not, and this new config option is activated, U-Boot removes the ATA node from the DTS before booting Linux, so the Linux IDE driver does not probe the device and crash. This is needed for buggy hardware (uc101) where no pull down resistor is connected to the signal IDE5V_DD7. Signed-off-by: Heiko Schocher <hs@denx.de>
