Hello,

I've been using u-boot as the boot loader for x86 qemu and some custom (e.g. non-default) boot commands. I recently upgraded from u-boot 2018.01 to 2018.11 and now my boot command fails because it doesn't look like u-boot is loading the driver for the ide device from which I'm attempting to load files.

For reference, I'm basically building the qemu-x86 config only with changes to the default boot scripts. Namely, I have:

#define CONFIG_BOOTCOMMAND \ "ide dev ${bootpart}; " \ "if run loadbootenv; then " \ "run importbootenv; " \ "fi; " \ "run doboot; "

The failure appears to occur when the script attempts to run "ide dev ${bootpart}", claiming the ide device doesn't exist. If I manually run the command "ide reset", and then "bootd" everything works fine, so I think this is being caused by the switch to using the device model for

Correct.

ide(?). I suspect this means that I need to make some changes to my boot command to get it to probe the ide driver, but I wanted to make sure I'm doing that the correct way. Should I simply add a "ide reset" as the first line of CONFIG_BOOTCOMMAND, or is there a more "correct" way to get u-boot to probe the driver?

Yes, adding "ide reset" is the correct way.
